eDLoran Enhanced Differential Loran

The Dutch company Reelektronika B.V. has, at the request of the Dutch Pilots Corporation (Nederlands Loodswezen), developed and tested successfully Enhanced Differential Loran (eDLoran) to backup GNSS in cases of jamming or spoofing of the satellite system. An unprecedented but required absolute accuracy of five metres has been achieved at sea and in the Rotterdam Europoort harbour area.
