[0002] RTK real-time dynamic measurement technology is a real-time differential GPS technology based on carrier phase observation. It is a breakthrough in the development of measurement technology. It consists of three parts: base station receiver, data link, and mobile station receiver. A receiver is placed on the base station as a reference station to continuously observe the satellite, and its observation data and station information are sent to the mobile station in real time through radio transmission equipment. While receiving GPS satellite signals, the mobile station GPS receiver receives the data transmitted by the base station through wireless receiving equipment, and then calculates the three-dimensional coordinates and accuracy of the mobile station in real time based on the principle of relative positioning.
