Sikker skibsnavigation uafhængigt af GPS

Frygten for de potentielle konsekvenser ved nedbrud af GPS, jamming eller de uønskede effekter på GPS af kraftige solstorme har sat fokus på den udbredte ensidige afhængighed af GPS og andre satellitsystemer med tilsvarende svagheder.

Farvandsvæsenet lancerede i denne uge et forslag om automatiseret positionsbestemmelse for skibe ved anvendelse af skibes radar, uafhængigt af GPS.

Forslaget blev fremlagt under et møde i IALA (The International Association of Marine Aids to Navigation and Lighthouse Authorities), der netop nu er samlet i København med Farvandsvæsenet som vært.

Det er IALAs kommite for e-Navigation med 130 deltagere, der denne uge diskuterer forskellige forslag om at sikre skibes navigation, uafhængigt af GPS.

Farvandsvæsenets forslag kaldes ’Enhanced RADAR Positioning’ og blev taget vel imod af e-Navigation kommiteen, sammen med det tilhørende forslag om udvikling af en ’Enhanced RACON’ til etablering af særlige fixpunkter til brug for automatisk stedbestemmelse via Radar.

Flere leverandører af Radar og Racon udstyr har under organisationen CIRM (the International Association for Marine Electronics Companies) udvist stor interesse for at arbejde videre med forslaget, med henblik på at få etableret internationale standarder. Farvandsvæsenet undersøger i øjeblikket muligheden for at udføre feltforsøg med denne teknik i forbindelse med EU projektet EfficienSea (Efficient, Safe and Sustainable Traffic at Sea).
