Abstract

Testing of hardware packages of sensors, actuators, and control electronics in the control loop for the IRS and SROSS satellites using motion simulators is reported. Simulation exercises and test results are described. Both air-bearing platforms and servo tables were used. The problems observed varied from interface incompatibilities and logic-level mistakes to onboard software malfunctions. unit-to-unit differences, and controller gain parameters. The importance of testing with hardware in a dynamic environment, is demonstrated
