Abstract
Considering the request of spacecraft's automatic rendezvous and docking with a non-cooperative target, a method of estimating the motional state based on Kalman filter is investigated. C-W equation is used to modeling the relative motion between satellites. In the case that a radar is taken as the measuring facility, the measurement equation is deduced. Autonomous determination of the relative orbit using extended Kalman filter is addressed. The simulation shows the effectiveness of the method and the influence of system yawp and sampling time to filter.
