上一个的继续,连续有九个压缩文件,大家可以打开解压后自己慢慢享用,这个都是本人调试通过了的,希望共同进步!-A continuation of a row has nine compressed file, everyone can open their own after extracting slowly to enjoy, this is my debug adopted, and I hope common progress!

The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS receiver is located at a well surveyed position and its (pseudo) range measurements are compared with the actual calculated range from this receiver to the SV s. The differences between measured ranges and calculated ranges at the reference receiver are applied as corrections to the ranges measured by other receiver(s) close by.
