Precise GPS dynamic measurement adopts carrier phase difference technology. Its standard measurement mode is that one GPS receiver is placed at a known point as a reference station for static measurement, and the other GPS receiver is placed on a carrier as a mobile station for dynamic measurement. Two receivers observe the same satellite synchronously, and then combine the observations of the two GPS receivers to obtain the coordinates and velocity of the mobile station relative to the reference station. This paper mainly introduces the process of using rtklib to realize precise dynamic positioning. The process includes reading observation files and navigation files, calculating the location of reference station, solving the location of mobile station, outputting the operation results, etc. it helps GNSS developers to quickly master rtklib
