Abstract
Satellite design involves the development of subsystems like telecommand, telemetry, attitude control, thermal control, structure, and payload. Testing the satellite on ground and qualification is an essential aspect to be considered while designing a satellite. A test system should be built to test and qualify all subsystems and their integrated behavior on ground. RSAT is a small satellite being developed at PES University with automatic identification system (AIS) as a payload. This paper presents the design aspects of such a test system for testing the attitude control system (ACS), which is flexible in terms of adding or removing any sensor or actuator. This paper is an attempt to present details on how the test system is made configurable for manual testing, automated testing, open-loop bench test, closed-loop attitude control testing and hardware-in-the-loop tests. The test system has been built as a generic tool making the system configurable for any satellite with ease.
