A NEW METHOD OF TESTING ADVANCED SPACECRAFT POINTING CONTROL INVOLVING FLEXIBILITY

In response to the strong need to demonstrate the validity of newly de veloped satellite attitude control logics, a new ground test method ha s been developed. This test method features a scale model called SSDM (Scaled Satellite Dynamic Model). SSDM behaves just like a satellite r eleased in non-gravity field and serves as the satellite attitude dyna mics portion in the control loop. This test method enables on-ground d ynamic qualification of advanced control laws which so far has been un available. As the first application of this method, robust filter cont rol loop for MUSES-B satellite has been tested.
