编程实现对GPS通讯信息的采集方法，将接收到的数据进行语义的解析，并在LCD上显示 当前的地理位置信息。...

利用C#编写的GPS伪距单点定位程序，可以根据星历数据和观测数据批量计算接收机坐标，内附测试数据和结果。

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

提出了利用精密单点定位(precise point positioning,PPP)技术进行海啸预警的方法,并利用TriP软件对实测浮标数据进行了处理,将得出的海面高数据和海啸波模型叠加进行了模拟分析。仿真结果表明,利用精密单点定位技术进行海啸预警,能够监测判断海啸的发生,并获得海啸波到达海岸的波高和时间,提供一定的预警信息。 -Made use of Precise Point Positioning (precise point positioning, PPP) technology for tsunami early warning methods and the use of Trip software buoy measured data were processed, will come to the surface of high tsunami wave model data and conducted a simulation analysis of superposition. The simulation results show that the use of Precise Point Positioning for the tsunami early warning, to monitor to determine the occurrence of the tsunami, and tsunami wave reached the coast, wave height and time, provide some early warning information.

对于WAAS系统的最终衡量标准是可用性强调了导航系统的运行经济性。它被计算为时间的WAAS系统提供位置固定的准确性，完整性和连续性的指定级别的分数。最低运行性能标准（MOPS）的WAAS指定必须在99.99999％的概率得到满足的差分改正导航解决方案的垂直防护等级（VPL）和水平防护等级（HPL）的计算。因此，真正的误差不能超过保护水平不止一次107秒钟。如果计算出的保护水平超过了相应的警报上限则报警被丢弃的操作无法继续进行。如果操作已经开始这个条件是连续性违反和复飞，必须进行。否则系统被声明为划时代不可用。
