RTKNetzwerken

RTKNetzwerken refers to networks of Real-Time Kinematic (RTK) Global Navigation Satellite System (GNSS) base stations. These networks provide precise positioning services to users over a wide geographic area. By establishing a network of continuously operating reference stations (CORS), RTKNetzwerken can calculate and broadcast corrections to roaming GNSS receivers, significantly improving their accuracy from meters to centimeters or even millimeters.

The core principle behind RTKNetzwerken is the correction of satellite signal errors. GNSS signals are subject to various errors, including atmospheric delays and satellite clock inaccuracies. RTKNetzwerken utilize the known, fixed positions of their base stations to determine these errors and generate correction data. This data is then transmitted wirelessly, often via cellular networks or radio modems, to mobile rover receivers. The rover receiver applies these corrections to its own GNSS measurements, thereby achieving high-precision positioning.

The benefits of RTKNetzwerken are numerous. They enable precise navigation and surveying for applications such as agriculture, construction, autonomous vehicles, and scientific research. Users can access these services through subscriptions, paying for access to the correction data. The density and distribution of base stations within an RTKNetzwerken directly influence the coverage area and the availability of precise positioning. Advances in network management and data transmission technologies continue to enhance the reliability and accessibility of these high-accuracy GNSS services.
