非常好的GPS基础技术文档，从伪距测量到载波相位，载到整周模糊度，相信会有收获的。-A very good GPS-based technical documentation, from the pseudo-range measurements to the carrier phase, containing the ambiguity, I believe there will be harvested.

伪距定位代码利用伪距测量用户位置的求解仿真-pseudorange positioning code uses pseudo-range measurements to solve the simulation the user s location
