电力GPS设备通信对时代码

一个基本的类 用于提取GPS数据中的经纬度，速度高度信息，功能较简单。-A basic category for the extraction of GPS data in latitude and longitude, speed, height information, a simpler function.

Powerful and Portable GPS application -- support Linux, Windows, Windows CE GPS navigation and Map management. -Powerful and Portable GPS application support Linux, Windows, Windows CE GPS navigation and Map management.

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

解析GPS 串口的NMEA报文的类。有GGA,GSA,GSV,RMC,RMB等报文的解析-GPS NMEA CLASS

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

GPS 捕获程序,采用FFT搜索算法,搜索1024个码相位.-GPS capture procedures, using FFT algorithm, search phase code 1024.

基于arduino的GPS地图导航系统 SPI接口。采用Atmega 328为主控芯片 需要采用滤波算法过滤 串口速率与GPS模块要设置一致，接线方式如下： //TFT SDA -> UNO 11 //TFT SCK -> UNO 13 #define TFT_CS 10 // Chip select line for TFT display #define TFT_A0 9 // Data/command line for TFT #define TFT_RST 8 // Reset line for TFT (or connect to +5V) #define TFT_LED A0 #define SD_CS 4 // Chip select line for SD card //SD MISO -> UNO 12 //SD SCK -> UNO 13 //SD MOSI -> UNO 11 //GPS tx - UNO rx //GPS rx - UNO tx #define BTNZOOMIN 2 #define BTNZOOMOUT 3

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
