faster algorithm for GPS signal Acquistion

GPS导航的源代码，vc源码，很实惠，希望下载-GPS navigation of source code, vc source code, it is affordable, I hope download

几篇介绍卫星位置和速度计算的论文，基于MATLAB的GPS选星分析及实验研究，GPS中的一种新的选星方法-Satellite location and a few introductory rate paper, the GPS-based MATLAB election analysis and experimental study of stars, GPS in a new method of election stars

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.

从Rinex格式的GPS观测文件（即O文件）中提取所需卫星的VC程序-Observations from the GPS satellites needed to document the procedures to extract

实现了GPS,BDS(北斗)时间转换,包括通用时,儒略日,GPS时,北斗时,年积日之间的转换,界面采用vc6.0编写,简洁,可最小化至系统托盘,可方便地用于GPS算法调试,数据处理中的时间转换.

This a GPS communication source code to interrupt the NMEA code though serial port. Very good code to study and apply it to your own program.-This is a GPS communication source code to interrupt the NMEA code though serial port. Very good code to study and apply it to your own program.
