Performance analysis of deeply integrated BDS/INS

Deeply BDS/INS integration has been shown to improved navigation performance under low signal-to-noise ratio and high dynamic situations by using INS aided BDS acquisition and carrier tracking. It's important to develop the research on deeply BDS/INS integration with the development of the BDS system. Herein, the decisive technologies in BDS/INS were investigated including INS aided BDS acquisition, tracking loop mechanism and performance evaluation criterion, the basic architecture for the deeply integrated was shown. The entire performance was simulated on a software receiver, Test results have reference value for engineering application.
