本文在分析GPS 软件接收机跟踪原理的基础上，首先比较码环与载波环不同鉴相器的性能，然后对二阶锁相环中不同环路参数设下的跟踪效果进行仿真分析，最后设计
了合适的码环与载波环路，并用实际采集的GPS 数据论证了所设计环路的有效性，为GPS 软件接收机跟踪环路的设计提供了参考。-Based on the analysis of GPS receiver tracking software on the basis of the principle, first compare the different code loop and carrier loop phase detector performance, and the different second-order PLL loop parameters set by the tracking simulation analysis, the final design the appropriate code loop and carrier loop, and with real GPS data collected demonstrated the validity of the design loop for GPS receiver tracking loop design software provides a reference.
