GPS M-89模块DATASHEET 串口连接原理图-GPS M-89 modules to connect serial schematic DATASHEET

The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS receiver is located at a well surveyed position and its (pseudo) range measurements are compared with the actual calculated range from this receiver to the SV s. The differences between measured ranges and calculated ranges at the reference receiver are applied as corrections to the ranges measured by other receiver(s) close by.

均匀线阵方向图形成，包含没有波束指向和30°波束指向，加切比雪夫权值（旁瓣幅度相同）-Uniform linear array pattern formation, with no beam pointing and 30 ° beam pointing, Gache Chebyshev weights (the same side-lobe amplitude)

在GPS定位过程中，常常需要对卫星的星历进行内插计算，本程序采用matlab编写的牛顿插值算法实现对星历内插计算。

该压缩包为GPS定位的基本原理，系统阐述了GPS定位的基本原理和过程，包括绝对定位，相对定位， 动态、静态定位的区别，单差，双差三差的组合，不同类型双频观测值间的线性组合，周跳探测与修复，模糊度的解算，知识点涵盖大部分GPS测量系统知识，是学习GPS以及进行GPS开发参考的好资料。

某国外大牛开源的软件GPS接收机源代码，可以用MATLAB进行仿真，相应的GPS中频数据可以在网上下载到，配套书籍是《软件GPS接收机》，大家可以自行百度PDF下载

GPS的资料,上来和大家分享,正做这个的朋友可以看看.-GPS information to share with you all up, friends are doing this can have a look at.
