说明：  在 Matlab 环境下， 编写了 GPS 信号产生、 时域滑动相关搜 索捕获、 并行频域搜索捕获和并行码相位搜索捕获程序， 用软件方式实现了 对 GPS 信号的捕获。 仿真结果表明， 上述三种方法都可以实现 GPS 信号的正确捕 获。(Analog slide correlation capture method)

GPS定位程序相关关键代码，标准单点定位、PPP，模型参数可以自己设置(GPS positioning procedures related to the key code, standard single point positioning, PPP, model parameters can be set up their own)

GPS载波相位测量中LAMBDA算法整周模糊度求解程序；是GPS姿态动态测量入门级算法。(ambiguity solution for gps in carrier measurement,is the basic algrithom for gps attitude measurement on the fly. )

基于ＥＧＭ２００８模型的重力观测点ＧＰＳ高程转换(GPS Height Transfrom Based on EGM2008 Model)

《软件定义的GPS和伽利略接收机》配套资料，实现中频GPS信号的“捕获”、“跟踪”、“导航解算”并且有各阶段的“绘图”，便于理解。需要“中频数据”才能运行。(" Software-defined GPS and Galileo receivers," supporting information, to achieve intermediate frequency GPS signals " capture" , " track" , " navigation solution," and there are various stages of " drawing" , easy to understand. Need to " IF data" to run.)

说明：  通过GPS接收机，实现动态或静态状况下的精确定位。(realize the precise position)

针对GPS发射信号的捕获程序，采用差分相干捕获方法(Fired for GPS signal acquisition procedure, differential coherent acquisition method)

GPS信号捕获的源程序设计，提供的信号捕获的原始算法实现(GPS signal acquisition of the source design, providing a signal acquisition of the original algorithm)

RS码的FPGA实现，verilog语言形式，好参考资料(FPGA realization of RS code, verilog language form, a good reference)

GPS开发经典工具，很有参考价值，你可以用它在PC平台接收数据包，这样就可以研究包结构知识(GPS development of classical tools, a good reference, you can use it in the PC platform for receiving data packets, so packets can study the structure of knowledge)
