| Abstract: | Beidou satellite navigation location system is China's first generation satellite navigation system.The star sensor is a high precision attitude-measuring instrument.On the basis of non-feedback federal filtering,Beidou navigation location system and the star sensor are used together in an integrated navigation system in order to set up the SINS/Beidou/star integrated navigation system.From the characteristics of Beidou and the star sensor,causes of delay and asynchronous problem in the instrumentation are analyzed,and a solution is proposed.Simulation shows that this integrated navigation system has high precision and good tolerance to faults.This shows application potentials for the Beidou system in defense industries. |
