SPACECRAFT ARCHITECTURE FOR DISTURBANCE-FREE PAYLOAD

摘要

The system of the present invention is a spacecraft architecture for precision motion control of a payload (10) while isolating disturbances and vibrations to the payload. The motion of the payload module is controlled by reacting on the support module (12) using non-contact actuators (14) disposed between the two modules. The motion of the support module is controlled to follow the payload module using external actuators (24, 26, 28, 30, 32) that react against the surroundings. This system achieves vibration isolation down to zero frequency and is not limited by sensor characteristics.
