精密GPS动态测量采用载波相位差分技术，其标准测量模式为，一台GPS接收机置于已知点，作为基准站来进行静态测量，另一台GPS接收机置于载体上，作为流动站来进行动态测量。两台接收机同步观测相同的卫星，然后将两台GPS接收机的观测值进行组合处理，就可以获得流动站相对于基准站的坐标和速度。本文主要介绍用RTKLIB 实现精密动态定位的过程，该过程包括观测文件和导航文件的读取、基准站位置的计算、流动站位置的求解、运行结果的输出，下面将分块讨论。(Precision GPS dynamic measurement using carrier phase difference technology, the standard measurement mode, a GPS receiver placed at a known point, as a base station for static measurement, another GPS receiver placed on the carrier, as a mobile station Perform dynamic measurements. The two satellites simultaneously observe the same satellite and then combine the observations of the two GPS receivers to obtain the coordinates and speed of the rover relative to the base station. This paper mainly introduces the process of realizing dynamic dynamic positioning with RTKLIB. The process includes reading the observation file and navigation file, calculating the base station position, solving the position of the mobile station, and outputting the result of the operation.)
