全球定位系统的重要信息，包括很多源代码附件，很是…

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测试程序12864液晶（并行方式）    可以得到经纬度，时间，対地速度，对地方向，是根据逗号结点来解析的程序。觉得作为刚开始学习gps的朋友可以下载，对于理解gps很有帮助。。。这个代码很不错。不过你自己可以继续修改。是学习的好程序

对GPS模块的数据处理本质上还是串口通信程序设计，只是GPS模块的输出遵循固定的格式，通过字符串检索查找即可从模块发送的数据中找出需要的数据，常用的GPS模块大多采用NMEA-0183 协议。NMEA-0183 是美国国家海洋电子协会(National Marine Electronics Association)所指定的标准规格，这一标准制订所有航海电子仪器间的通讯标准，其中包含传输资料的格式以及传输资料的通讯协议。

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.
