GPS Knowledge Base: What is RTK Technology

source:Industry News release time:2022-08-18 Hits:     Popular:realtime gps tracker online

  

  Conventional GPS measurement methods, such as static, fast static and dynamic measurements, need to be solved after the fact to obtain centimeter-level accuracy, while RTK is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field. It uses carrier phase dynamic real-time The differential (Real-time kinematic) method is a major milestone in GPS applications. Its appearance brings a new dawn to engineering stakeout, topographic mapping, and various control measurements, and greatly improves the efficiency of field operations.

  High-precision GPS measurement must use carrier phase observations. RTK positioning technology is a real-time dynamic positioning technology based on carrier phase observations. It can provide real-time three-dimensional positioning results of the station in the specified coordinate system, and achieve centimeter-level accuracy. In RTK operation mode, the base station transmits its observations together with the station coordinate information to the rover through the data link. The rover not only receives data from the base station through the data link, but also collects GPS observation data, and forms differential observations in the system for real-time processing, and gives centimeter-level positioning results, which lasts less than one second. The rover can be in a static state or in a moving state; it can be initialized on a fixed point before entering the dynamic operation, or it can be powered on directly under dynamic conditions, and complete the search and solution of the ambiguity in the dynamic environment. After the solution is fixed over the weekend, real-time processing of each epoch can be performed. As long as the tracking of the phase observations of more than four satellites and the necessary geometry can be maintained, the rover can give centimeter-level positioning results at any time.

  The key of RTK technology lies in data processing technology and data transmission technology. RTK positioning requires the base station receiver to transmit the observation data (pseudo-range observation value, phase observation value) and known data to the rover receiver in real time. Large, generally require a baud rate of 9600, which is not difficult to achieve on the radio.
