用matlab实现的超宽带物理层的仿真 。

gps基线解算基础函数，包括伪距定位，差分定位，坐标转换等

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.

资源描述 无意中下到的CS版GPS程序，可以学习代码 只有本地的SqliteDB

ns2网络仿真中超宽带的实现，该文件是对ns2的patch文件，很好的哦-ns2 network simulation over the realization of broadband, the file is the patch file ns2, oh well

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

对C/A码的相关在频域中的matlab实现仿真，大家交流啊，-Of C/A code correlation in the frequency domain realize matlab simulation, the exchange of everyone ah,

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.

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

测试gps接受设备正确性代码.运行exe文件后,可以查看到通讯设备是否正常-gps acceptance testing equipment correctness code. Run exe file, they can check whether the communications equipment to normal

关于GPRS的通讯程序,对GPRS协议及软件实现的功能得到了很大的加强.要好好研究啊.-on GPRS communication procedures, GPRS agreement and the right software to function much strengthened. We should carefully study ah.
