中文说明：首先仿真生成北斗B1I中频信号，将其保存到文件中。调用捕获程序对1~37PRN编号卫星进行捕获处理，保存捕获结果。对捕获结果进行整理，选取相关峰值较大的卫星转入跟踪通道。对各跟踪通道进行跟踪处理，使用PLL和DLL进行环路跟踪，持续得到跟踪结果。
English Description：
Firstly, if signal of Beidou b1i is generated by simulation and saved to file. The capture program is called to capture the 1 ~ 37prn satellites, and the capture results are saved. The acquisition results are sorted out, and the satellite with larger correlation peak is selected to turn into the tracking channel. Each tracking channel is tracked, PLL and DLL are used for loop tracking, and the tracking results are obtained continuously.
