ANNEXURE: A

Details of thermal simulation / thermal instrumentation on spacecraft/ electronics packages for conducting thermal testsThermal tests are categorized into

Thermal balance test(TBT) – for verifying thermal design of spacecraft and demonstrating the ability of thermal control system in maintaining temperatures of spacecraft within specified limits.

Thermal vacuum performance test (TVP) - for verifying the electrical performance of spacecraft under vacuum and at the extreme hot and extreme cold qualification / acceptance temperatures.

Typical thermal instrumentation for conducting above test is as follows:

Temperature sensors (Thermistors, Platinum Resistance Temperature sensors)

Electrical heaters ( Foil heaters, tape heaters)

Infrared lamps are used in front of spacecraft panel at a distance of 250-300mm.

Test temperature sensors – generally T-type thermocouples are also instrumented with redundancy at critical locations for temperature control and additional monitoring purpose.

The heaters and IR lamps are divided into number of temperature control zones depending up location of subsystems and their extreme temperature limits, kind of thermal control system etc.

Spacecraft is placed inside the vacuum chamber. Chamber temperature may vary from -100ºC to +100 ºC. vacuum maintained at 10-5 bar or better.

Thermal test instrumentation is connected to computer based data acquisition and power supply / control system (TDAC). Temperatures of all the subsystems are continuously monitored and controlled by TDAC using PID control loop as shown in following figure
