      Articulated payloads on spacecraft, such as antenna telemetry systems and robotic elements, impart reaction torques back into the vehicle which can significantly affect the performance of other payloads. These disturbances can degrade the quality of the data obtained by other on board experiments and systems. This paper discusses ways to minimize the reaction torques of articulated payloads through command shaping algorithms and unique control implementations. The effects of reaction torques encountered on the LANDSAT satellite are presented and compared with simulated and measured data of prototype systems employing these improvements.
