摘要：

The filtering process of satellite attitude/attitude rate estimation is discussed using only star sensors in the paper. Considering characteristics of the vector observation, a real-time predictive filter for three-axis attitude estimation is given. An improved algorithm, which simplifies the restrictive condition, is presented based on predictive filter. The nonlinear filter accurately estimates satellite attitude by predicting uncertainty in the dynamics equation one step ahead. The simulation results demonstrated both feasibility and robustness of the filter.
