Conventional GPS measurement methods, such as static, fast static and dynamic measurement, need to be solved afterwards to obtain centimeter level accuracy. RTK is a measurement method that can obtain centimeter level positioning accuracy in real time in the field. It adopts the carrier phase dynamic real-time difference (Real time Kinematic) method, which is a major milestone in the application of GPS. Its appearance has brought new dawn for engineering lofting, topographic mapping and various control surveys, It greatly improves the field work efficiency.
High precision GPS survey must adopt carrier phase observation value. RTK positioning technology is a real-time dynamic positioning technology based on carrier phase observation value. It can provide real-time three-dimensional positioning results of survey stations in the specified coordinate system and achieve centimeter level accuracy. In the RTK operation mode, the base station transmits its observation value and station coordinate information to the mobile station through the data link. The mobile station not only receives the data from the base station through the data link, but also collects the GPS observation data, forms the differential observation value in the system for real-time processing, and gives the centimeter level positioning results, which takes less than a second. The mobile station can be in a static state or in a moving state; It can be initialized at a fixed point before entering the dynamic operation, or it can be started directly under dynamic conditions, and the cycle ambiguity can be searched and solved under the dynamic environment. After the known number solution is fixed throughout the week, real-time processing can be carried out for each epoch. As long as the tracking of more than four satellite phase observations and the necessary geometry can be maintained, the mobile station can give centimeter level positioning results at any time.
The key of RTK technology lies in data processing technology and data transmission technology. During RTK positioning, the reference station receiver is required to transmit observation data (pseudo range observation value, phase observation value) and known data to the mobile station receiver in real time. The amount of data is relatively large, and generally requires 9600 baud rate, which is not difficult to achieve in radio.
