Abstract :
This paper has described the determination method of long term TWT gain stability. If there is a change in gain, it can be detected using available spacecraft level on-orbit measurements and then quantifies the resulting impact on linearity performance and it concluded TWT gain change can be detected using available satellite telemetry, provided that the TWT operation meets the criteria described.
