GPS signal Pulling in Tracking range

GPS模块开发：vb、rs232串行通信控制-GPS Module Development: vb, rs232 serial communication control

GPS单点定位程序，可实现卫星坐标计算，地面点坐标计算，精度指标计算和输出到Excel。

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.

关于GPS接收模块的资料。有详细的功能特性，组成结构及引脚说明等。-GPS receiver module on the information. Have detailed features of the composition of the structure and pin descriptions.

简单的使用c语言，调用GPS接口数据， 并通过1602液晶屏显示出经纬度，使用的芯片是80c51，还可以扩展显示高度，速度等信息，程序可以直接使用keil软件烧录到芯片上。

基于自主开发的A/D芯片的vc测试程序，希望对大家有帮助-based on the self-development of the A/D chip vc testing procedures, we hope to help
