摘要
主要研究惯性信息辅助卫星接收机跟踪环路的结构形式，分析惯性信息辅助后卫星接收机的等效带宽和动态跟踪性能。通过仿真验证表明，采用惯性信息辅助能够有效提高卫星接收机在高动态、强干扰条件下的跟踪性能。
This article mainly researched the structure of the carrier tracking loop in the Inertial aiding GPS receiver, Analyzed the equivalent Loop bandwidth and tracking performance of carrier tracking loop. Then the simulation result illuminated that the tracking performance of Inertial aiding GPS receiver was improved obviously in the high dynamic and strong jamming conditions, compared with the common GPS receiver.
