  • GPSreceiver-matlab--code
    matlab下完整的gps软件单通道接收机程序,从捕获跟踪到位置解算。运行需中频数据文件太大无法上传,在gps类网站上提供下载。postprocessing.m为主程序。 对部分评论的解释: 1. 运行主程序前用init.m进行变量参数设置,生成后面运行的结构体 2. 程序出错,是由于缺少数据文件。 3. 从网上下载的GPS中频数据文件,由于格式不同,程序是需要调试的。这里用的是.bin格式的。 剩下事的没有什么需要更改的了,好运。我是运行调试通过后发上来的 (matlab under a complete the gps software single-channel receiver program, from the acquisition and tracking to position solver. Run the required the IF data file is too large to upload, download gps on the class website. postprocessing.m main program. Explain some of the comments: 1. Structure variable parameter settings with init.m before running the main program to generate run later. Procedural error is due to the lack of data files. GPS IF data files downloaded from the Internet, because of the different formats, the program is needed to debug. Here is the format. Bin. Remaining there is no need to change a thing, good luck. I was running after debugging through made up)
