代码说明:

此代码是仿真GPS L1 信号捕获。首先,它生成 CA 代码和相关的伪代码,然后乘以载波。然后,仿真信号的频谱被绘制。最后,频率偏移被加到了信号,本地通过与仿真信号的相关运算和使用已知的pn码来获得即时的起始代码和频率偏移量。

  • zigzag error
    zigzag纠错码是一种非常简单但却具有非常优秀性能的码。非常适合用于中码率或者高码率编码的系统。此为一位教授提供的源码。-zigzag error-correcting code is a very simple but has a very excellent performance of code. Very suitable for use in bit-rate or high bit-rate coding system. This is the source provided by a professor.

  • android gps jni源码
    android gps jni源码函数调用了hw_get_module加载硬件适配模块.so文件,接着通过hw_device_t接口调用open()函数,实际执行了gps/loc_api/libloc_api/gps.c定义的open_gps函数,然后调用gps_device_t接口的get_gps_interface函数,此函数也是在gps.c中定义的,最后返回HAL层中loc_eng.cpp文件的sLocEngInterface,从而打通了上层到底层的通道。

    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.

    以前用VB,C#等很轻松将GPS信息解码。但是最近要使用C语言,(网上有一个VC的按位解的)苦于C操作字符串的难度,请各位大侠放出一份C代码解GPS。 我先贴上我用C解的代码,是直接将VB和C#的思路转过来的。 现在可以读出经度或纬度-before using VB, C#, etc. is easy to decode the GPS information. However, the recent use of C language, (the Internet by a VC-Solutions) cited a string C operation difficult, Please Shanhaiguan released a GPS Solution C code. I affixed my first solution with C code directly to C# and VB of the ideas turn. Can now read latitude and longitude
