gprs通信对数据进行校验,本程序能够精确校验GPRS数据

RTK信息上传到服务器,然后其他设备通过GPRS网络访问服务器传输上来的数据，此代码是服务器端的代码，用来在服务器端接收和分发RTK数据！

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.

zigzag纠错码是一种非常简单但却具有非常优秀性能的码。非常适合用于中码率或者高码率编码的系统。此为一位教授提供的源码。-zigzag error-correcting code is a very simple but has a very excellent performance of code. Very suitable for use in bit-rate or high bit-rate coding system. This is the source provided by a professor.

GAMIT软件中，track模块可以实现GPS动态定位解算。
