基于c51单片机的GPS通讯 汇编程序 开发

包括程序源码、ATK-NEO-6M GPS模块使用手册、原理图、官方文档、相关软件，非常适合初学者做开发

GPS时间转换程序，采用C#Windows编写，有良好的界面布局，输入年月日可以准确地转换成GPS周、周内日以及年积日，对从事GPS研发人员很有帮助。

不用说了，很好的GPS数据采集程序，完整实用美观的界面-Needless to say, and a very good GPS data collection procedures, a complete interface aesthetic practical

GPS软件接收机的源码，实现信号跟踪、捕获、电文解调、定位解算等功能，有助于学习卫星导航的同学加深对GPS接收机工作原理的理解，也可作为核心代码扩展为GPS接收机工作原理演示程序。

procedure TfrmMain.DrawSatInfo(gps: TGPSInfo; pbx: TPaintBox); var   i: integer;   r: integer;   dx,dy: integer; begin   r := pbx.Width div 2;   for i:= 1 to 12 do begin     if gps.SatInfo[i].PRN 0 then begin       dx := r + Round(r*(90-gps.SatInfo[i].EL)*sin((gps.SatInfo[i].AZ - 90)*Pi/180)/90);       dy := r + Round(r*(90-gps.SatInfo[i].EL)*cos((gps.SatInfo[i].AZ - 90)*Pi/180)/90);       dx := dx - 8;       if dx < 0 then dx := 0;       if gps.SatInfo[i].SN > 20 then begin         pbx.Canvas.Font.Color := clBlue;         pbx.Canvas.TextOut(dx,dy,inttostr(gps.SatInfo[i].PRN));       end else begin

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.

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

资源描述该代码主要实现的是对一个网形进行平差计算，所采用的语言为Csharp，本代码可以作为初学C#进行练手，也可以通过本程序了解GPS网平差处理的基本过程，希望对GPS研究者有所帮助。
