基于自主开发的A/D芯片的芯片初始化程序，vc编写，希望对大家有帮助-based on the self-development of the A/D chip chip initialization procedures, vc prepared, and I hope to be helpful

最短路径分析的控件,首先使用regsvr32 程序注册该动态连接库,然后在vb中直接使用该动态链接库.程序中有相关说明,具体文件可以查看相关程序.-shortest path analysis controls, the first to use regsvr32 procedures for the registration of the dynamic link library, and then vb direct use of the dynamic link library. Procedures are related note, can view specific documents related procedures.

用Matlab将Radio Frequency（RF）收发模块进行模型化。非常少见用Matlab对RF的建模-Matlab will use Radio Frequency (RF) transceiver module model. Very rare with Matlab modeling of RF

用Matlab仿真turbocode的算法，即编码结构-using Matlab turbocode algorithm, namely coding structure

gps接收端源码以及1个test列子，提供简单的经纬度，速度，时间等GPS数据信息-gps receiver as well as a test source Liezi, providing a simple latitude and longitude, speed, time GPS data

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.

自己封装的能解析出GPS数据中的$GPRMC数据，获得经纬度信息，时间，日期等等。 可直接调用我封装的GPS类（已编译通过）-Their own package to resolve the GPS data in the $ GPRMC data, access to latitude and longitude information, time, date and so on. I can directly call the GPS package category (compiled through)

在利用GPS卫星进行单点定位过程中，需要进行电离层与对流层等误差的计算以及卫星高度角的计算，卫星高度角越高受观测误差就相对较小，本程序采用高度角随机模型加权，电离层采用K8模型加以改正，希望对GPS研究的朋友有帮助。
