The installation of a range-range positioning system due to interferance of the GPS signal in this location. Special care was taken in selection of the AXYLE beacon sites
Dredging maintenance operations were hampered due to strong interferance of the GPS signal.
Reliable uninterrupted reception of the GPS signal (L1 and L2) was not possible and consequently the dredger was left without positioning.
