10.4.1 Model Philosophy

What was presented earlier is the workow from the conceptual level to the

delivery of a ight-worthy payload to the satellite project for nal integration

with the satellite FM. Every satellite project has a model philosophy to ensure

all the subsystems and the satellite bus are tested to develop condence that the

total system will perform as per the planned mission goals. In the early years

of satellite building, a number of hardware models were developed to ensure

satellite design is robust. To qualify the structural design and to correlate

with the mathematical model, a structural hardware model is developed, which

includes mechanical dummies (to simulate mass) of all the subsystems. ...
