Study on the SINS/GPS Integration Navigation System Simulation

Cheng Zhang

Abstract

During the development of SINS/GPS integrated navigation system,field trial can not be conducted because of real limitations. In general,the simulation is used in the process of integrated navigation system design and validation. In the paper,the wander azimuth mechanization under Matlab/Simulink was used for c SINS (strapdown inertial navigation system ) computation. The pseudo-range output of the GPS receiver was taken as measurement. Then,the state and measurement equations were set and filtering fusion was conducted in earth center earth fixed frame,and singular value observability analysis was made. The numerical simulation shows that satisfactory performance is achieved by the designed integrated navigation system.
