software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

drive the hotwire low

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

drive the hotwire low

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

drive the hotwire low

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

drive the hotwire low

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

drive the hotwire low

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

drive the hotwire low

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

drive the hotwire low

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

drive the hotwire low

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

wait 5 seconds

drive the hotwire low

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Determining Altitude

calculateAltitude(pressure temperature)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Driving Hotwire at Glider Deploy

once the altitude is no longer greater than 400 meters drive the hotwire high

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

determine the pressure ratio and take the logarithm of it

if the pressure ratio is negative multiply it by -1

multiply the pressure ratio by the temperature and the gas constant

divide it by the gravity and thatrsquos the final altitude

Determining Velocity

calculateVelocity(staticPres stagPres)

assume air density is constant 1225 kgm^3

vel = sqrt(2density(stagPres-staticPres)

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

Software Development Plan

Presenter Eliza Dellert

Collect functional code

used in previous projects

Assemble electrical

prototype and then start

testing and debugging

code

GPS and data storage

will be implemented first

to allow full telemetry

testing on rocket

launches

Set synchronous

milestones with electrical

team With these methods in

mind we should have a

functional flight

software by the time

the first physical

prototype is complete

and ready for testing

This allows immediate support

for the thermistor MS5611

and radio

During this stage team

members will be assigned to

research and improve upon a

component to insure efficiency

Once new electrical builds are

completed we will test code for

the added components

CanSat Integration and Test

Overview

Environmental Testing Thermal Test Procedure (CETR 42) 1 Place CanSat into the thermal chamber

2 Turn on the CanSat

3 Close and seal the thermal chamber

4 Turn on the heat source

5 Monitor the temperature and turn off the heat source when the internal

temperature reaches 60C and turn on heat source when the temperature

drops to 55C

6 Maintain the temperature for two hours

7 Turn off heat source and perform visual inspection and any functional

tests to verify the CanSat survived the thermal exposure and can operate

as expected

8 With the CanSat still hot test any mechanisms and structures to make

sure the integrity has not been compromised

9 Verify epoxy joints and composite materials still maintain their strengths
