一个可以实现GPS模块通讯的软件源码，适合于目前所有GPS模块。...

GPS定位是利用卫星位置来实现对地面目标点的点位，本程序采用C#编写，将GPS定位与地图显示之间进行联系起来

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.

此程序为GPS软件接收机的源码，能够对匹配滤波后数据实施捕获和跟踪算法，对理解GPS接收机原理有很大帮助。-procedure for the GPS receiver software source code, to the matched filter after the implementation of data capture and tracking algorithm, the GPS receiver understanding will be of great help.

基于部标808协议的GPS平台压力测试工具，通常用于平台压测用，检测GPS服务器解析平台测试压力的工具

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.
