DGNSS radiobeacons – the European frequency problem

David Last and Birol Erdem Turhan

Abstract:	The frequency band for the radiobeacon DGNSS service in Europe is crowded with marine and aeronautical beacons. Finding the optimum channel for a new DGNSS beacon is a complex process. Atmospheric noise and the groundwave and skywave components of wanted and interfering signals must be estimated over large areas. The paper describes a novel approach, implemented in software, that is demonstrated allocating channels for 12 new radiobeacons around the British Isles. The resulting DGNSS system causes and receives much less interference, and has a significantly larger operating area, than can be achieved using the traditional radiobeacon design approach.
