IALA's New European DGNSS Radiobeacon Plan

David Last, Erdem Turhan and Nick Ward

Abstract:	The rapid development of differential GNSS transmissions from maritime radiobeacons in Europe has further increased the occupancy of an already over-crowded frequency band. This has resulted in interference between stations, with substantial reductions of coverage. The paper describes the process by which the channels of this band are being reallocated throughout the European Maritime Area. This reorganisation has taken careful account of the groundwave and skywave propagation of both wanted and interfering signals and of the distribution of atmospheric noise. A novel algorithm has been developed for reallocating the frequencies. The resulting band plan, scheduled for introduction early in 2001, is shown to offer substantially increased coverage for DGNSS radiobeacons while preserving the performance of the remaining marine and aeronautical direction-finding stations.
