高敏度GPS接收机的研究

Research on High-sensitivity GPS Receiver

GPS(Global positioning system,全球定位系统)目前已经得到了广泛的应用,尤其是高敏度GPS接收技术已成为当今的研究热点。本文主要介绍了GPS的信号特点及目前高敏度GPS的需求,设计了高敏度GPS接收机系统,对高敏度GPS接收机的捕获跟踪进行了仿真分析和研究。

GPS has been applied to a wide range, especially the high-sensitivity GPS receiver technology has been become the research focus. The feature of the GPS signals and the requirement of the high-sensitivity GPS were introduced in this paper. A high-sensitivity GPS receiver system was designed, and the capturing and tracking of the high-sensitivity GPS receiver were also simulated and researched.
