将互相关GPS接收机的C1

基带测量信号处理的算法：1.最小二乘曲线拟合法2.线性滤波方法3.非线性滤波方法非线性滤波方法就是和深组合导航系统中利用联邦卡尔曼滤波的方法是一样的，基带信号处理相当于联邦卡尔曼滤波中的局部滤波器

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.

gps/gprs 技术文档，可以参考实现的说明原理，实现即时通信技术-gps/gprs technical documentation, you can reference implementation description of the principle of instant communication technology

此代码为任何nmea gps模块制造，并专门用于nmea gr-87 gps模块。

在车辆上固定安装GPS接收机可以做车载GPS，采用车载GPS可以实现对GPS定位的动态测试，以便了解动态作业环境下的定位精度等性能，程序实现了车载GPS导航系统的设计。

通过串口接收数据，分析GPS数据，分析出当前时间，设置本机时间等。-Receive data through serial analysis of GPS data, analyze the current time, set the local time.

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.
