使用C语言编写的计算GPS卫星在任意时刻的三维速度的程序

基于功率倒置算法的GPS抗干扰天线仿真以及高斯噪声的产生函数,LMS收敛，matlab源码，成功运行，效果不错，值得参考

mo的GPS例子程序，含有详细的注解。可以保存打开GPS文件，使用标准NEMA1830报文格式。-mo GPS procedures example, contain detailed footnotes. GPS can be preserved for open document, the use of standard text format NEMA1830 reported.

以前用VB，C#等很轻松将GPS信息解码。但是最近要使用C语言，（网上有一个VC的按位解的）苦于C操作字符串的难度，请各位大侠放出一份C代码解GPS。 我先贴上我用C解的代码，是直接将VB和C#的思路转过来的。 现在可以读出经度或纬度-before using VB, C#, etc. is easy to decode the GPS information. However, the recent use of C language, (the Internet by a VC-Solutions) cited a string C operation difficult, Please Shanhaiguan released a GPS Solution C code. I affixed my first solution with C code directly to C# and VB of the ideas turn. Can now read latitude and longitude

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.
