Abstract1983 Global Positioning Systems (GPS) were made

available to the publicPeople rely heavily on GPS todayGoal: Implement a temporary system in the event the

satellites become inoperableProposed Solution: VHF Omnidirectional Radial (VOR)

Long Term Sponsor Goal

Use high altitude balloons to function as temporary satellites

IntroductionProblems to be Solved

Provide an alternative solution to GPS failure

Past Projects/Customer NeedsNo groups at Wright State University have attempted this projectAny person/business who wants a backup to GPS

Our Customers/Market VolumeAnybody in the government/private sector relies on GPSMarket volume would be high due to the fact GPS is so widely used

DemandThere is no backup system currently implemented so the

government/private sector would be interested in this product

ConstraintsLaws

FCC and HAM radio license rules. Additionally, Federal Aviation Administration rules must be adhered to.

Manufacturing/SustainabilityLightweightSustain weather conditions (i.e. temperature, high wind,

precipitation)Withstand Landing

CostThis project has to meet certain budget criteria, but our funds are

sufficient due to our sponsors

Project Goals/DeliverablesImplement a VOR positioning system as a supplement to

GPS.Plan A – Track balloon location using VOR radials from three

different stationsPlan B – Similar to Plan A, signal strength will be used to

triangulate a position

Project Goals/Deliverables

Project Goals/Deliverables Short Term Goals:

Small ScaleImplement phase shift/signal strength positioning in the laboratory

Moderate ScaleImplement phase shift/signal strength positioning around/near campus

Large ScaleImplement phase shift/signal strength at altitude with balloon

Potential DifficultiesThe transmitting signal does not produce a strong enough

signal to analyzeEquipment for VOR is highly specialized to aircraft

instrumentsThe lack of fox hunting skills

Project Plan and ScheduleScheduled meeting times: Wednesday and Saturday

Launch Dates and other meetings subject to existing HAB team launches

Proposed Budget• This project has negligible budget concerns due to

sponsor interest• At this point in the schedule we have not determined all

necessary parts we need.
