Abstract :
In order to meet the requirements of high precision orbit determination and prediction for the safe and pinpoint lunar soft landing, the paper presents an autonomous navigation based on SINS (strapdown inertial navigation system) /DOPPLER Radar/Radar Altimeter integrated navigation system. According to the error characteristics of each sensor, an effective information fusion algorithm is designed. The excellent result of vehicle experiment indicates that the integrated navigation has high precision, the system design method is successful, and it has better value of engineering application.
