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.

一个适合制作GPS定位系统的显示程序，里面有完整的程序注释，可供参考-A GPS positioning system for the production of the display program, there are complete notes of the proceedings is available for reference

这个程序是matlab用来来对锁相环（PLL）进行仿真的，这样的选择基于多方面的考虑-This procedure is used Matlab to the phase-locked loop (PLL) simulation, This choice is based on a number of considerations

利用卡尔曼算法对GPS  数据进行滤波、预测，利用MPU6050与HMC5883L对其姿态进行结算，实现了GPS导航功能，适合刚入门的四旋翼爱好者研究。
