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.

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。
