RTK CLUE uses mobile radio communication to send RTK correction data from regional fixed RTK base stations to vehicles. Correction data is needed in order to automatically steer with an accuracy of +/- 2 cm, or to use high-precision correction data for other applications, such as automatic section control.
Each vehicle receives its RTK correction data from a single base station. In fact, from a specific base station, which offers the best correction data for the respective vehicle. Thereby the best results are scored within a radius of 30 km. In order to increase the coverage, RTK CLUE connects single RTK base stations via the Internet to an RTK CLUE cluster.
The number of connected RTK base stations determines the size and thereby the individual coverage of the RTK CLUE Cluster.
If the farmer's fields of activity are located within the signal range of different RTK CLUE base stations belonging to a RTK CLUE Cluster, the switch between one base station to a physically closer base station happens automatically. However, data exchange with a farm management portal must be activated.
Alternatively the user can comfortably select the closest RTK CLUE base station with the RTK CLUE Manager on his smartphone or tablet. Furthermore, additional useful information is provided, e.g. the base station's status or the Rover's connection details.
