Abstract:
The Command and Control Subsystem for a commercial satellite lacked software command constraint checks. A gyro sensitivity setting that was incompatible with on-orbit testing of the thrusters resulted in a severe spin. Recommendations involve allowable command parameters, walkthroughs of critical mission command sequences, and use of a system testbed facility.
