Then the tracking effects with different loop patameters are simulated and compared. At last,a couple of discriminators are selected and proper loop parameters are designed to track actual GPS intermediate frequency signal,and the tracking results validate the design.
在分析GPS跟踪原理的基础上,对比码环与载波环不同鉴相器的性能,然后在不同环路参数下对跟踪效果进行了仿真比较,最后选择一组鉴相器并设计合适的环路参数,对实际采集的GPS中频信号进行跟踪,跟踪结果验证了设计环路的有效性。
