Abstract The GPS-RTK measuring technique is a real-time differential positioning technique based on carrier phase observation with the combination of global position system(GPS) and real time kinematic(RTK).The application and popularization of it have greatly improved the accuracy and efficiency of measuring points of hydrological measurement.This paper focuses on the structure,principle and measuring process of GPS-RTK measuring technique and its comparative advantages in hydrographic measurement.
