Simulation of the Tightly-Coupled SINS/GPS Based on a GPS Software Receiver
摘要
Abstract
In order to systematically verify the performance of SINS/GPS tightly-coupled system ,based on a GPS software receiver ,and a simulation system is constructed .The sim-ulation system consists of a trajectory generator ,a GPS IF signal simulator ,an IM U signal simulator ,a GPS software receiver ,a SINS navigation solver module ,a Kalman filter ,a navigation performance analysis module and other components .The detailed design of the ac-quisition and tracking algorithm of GPS software receiver ,SINS solution and Kalman filter based on pseudorange and pseudorange rate is provided .The simulation results show that , tightly-coupled integrated navigation system has a better convergence ,can control accumula-ted errors of SINS from a certain extent ,so it has a better navigation performance .And the system can meet the needs of tightly-coupled integrated navigation system performance veri-fication .The simulation platform can also be employed for the following research on ultra-tightly-coupled SINS/GPS .关键词
