GPRS部分源代码，一部分常用AT命令的代码实现，比如，打电话，发短信等-GPRS part of the source code, part of the AT command used a code, for example, make phone calls and send text messages, etc.

以前用VB，C#等很轻松将GPS信息解码。但是最近要使用C语言，（网上有一个VC的按位解的）苦于C操作字符串的难度，请各位大侠放出一份C代码解GPS。 我先贴上我用C解的代码，是直接将VB和C#的思路转过来的。 现在可以读出经度或纬度-before using VB, C#, etc. is easy to decode the GPS information. However, the recent use of C language, (the Internet by a VC-Solutions) cited a string C operation difficult, Please Shanhaiguan released a GPS Solution C code. I affixed my first solution with C code directly to C# and VB of the ideas turn. Can now read latitude and longitude

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。
