JT808 GPSServer终端模拟程序

此代码是仿真GPS L1 信号捕获。首先，它生成 CA 代码和相关的伪代码，然后乘以载波。然后，仿真信号的频谱被绘制。最后，频率偏移被加到了信号，本地通过与仿真信号的相关运算和使用已知的pn码来获得即时的起始代码和频率偏移量。

本程序对GPS的选星进行了模拟。给出7个可见星的信息，选则其中最好的四颗。-This procedure carried out on the GPS satellite simulated election. Seven visible stars are given information, the election is the best of four.

几篇介绍卫星位置和速度计算的论文，基于MATLAB的GPS选星分析及实验研究，GPS中的一种新的选星方法-Satellite location and a few introductory rate paper, the GPS-based MATLAB election analysis and experimental study of stars, GPS in a new method of election stars
