用Matlab仿真turbocode的算法，即编码结构

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编程小程序我觉得很不错,供大家参考.有不足之处请指出.-A gps application writen by myself,sharing with you,if there are any problem,please point out to me!

ST公司GPS设计方案,全球卫星定位系统gp新手必备。包括10多个文档资料。-ST Company GPS design, global satellite positioning system must gp novice. Including more than 10 documentation.

在利用GPS卫星进行单点定位过程中，需要进行电离层与对流层等误差的计算以及卫星高度角的计算，卫星高度角越高受观测误差就相对较小，本程序采用高度角随机模型加权，电离层采用K8模型加以改正，希望对GPS研究的朋友有帮助。

提供GPS参考站的数据结构，主要包含卫星星历结构，GPS卫星定位过程的一些模型参数，如电离层与对流层等，对初学GPS的人很有用。
