This part is done separatelyfor each subsystem i.e. power, mechanical, computer, science, thermal.Step 1: General definition.Subjective description and a few numbersStep 2: Numbers and ranges.Focus in on defining the problem. Step 3: Subsystems.Repeat step 2 for every subsystem, tracing from system requirements.012GORequirements LevelAn Example from Class: IcarusGoal (G1)The BalloonSat Aquintus shall ascend to an altitude of approximately 100,000 feet to carry out scientific experiments that will measure tilt of the satellite, forces acting upon it, wind speed, and solar energy to better understand the conditions in which high altitude
