KINEMATIC ORBIT DETERMINATION OF GEO SATELLITE BASED ON KALMAN FILTERING
基于Kalman滤波的GEO卫星运动学定轨

Considering the features of the motion of GEO(Geostationary Earth Orbit) satellite,Kalman filtering by using constant velocity model as state equation is proposed.When there exists systematic errors,forward and backward filtering is used,and when not,forward filtering.And the idea behind forward and backward filtering is that,firstly,using forward filtering estimates systematic error parameters,then the values obtained are used to do backward filtering.The simulation results show when there exists only rand...
