As an air carrier widebody transport freighter was crossing the north atlantic ARTCC called to ask about the coast-in point. The flight crew gave the controller the planned point, not the actual point and then the controller corrected them and informed them that a report of a potential gross navigation error would be made by ATC.

Narrative:
Crossing 52 degrees north, 40 degrees west, I gave a position report to gander radio and included an incorrect fix. Instead of calling the coast in fix as gander VOR, I called cymon. Cymon was on my filed ATC clearance, but gander VOR was on my track message nat 'east.' gander radio called us via SELCAL and asked us to confirm -- gander or cymon? At this time I still thought the coast in fix was cymon, but I started to check because of gander's level of interest. Shortly thereafter gander radio called again and said the fix is gander VOR and that gander center was filing the appropriate report. When I asked what type of report was being filed I was told it was an 'ATC intervention to prevent a gross navigation error.' I have flown many atlantic xings and this is the first time I have ever made this type of error. I contribute, to a large degree, the reason for this situation to fatigue. During this sequence of trips, I have had no schedule to count on and crew staffing is not adequate enough to cover the trips sold.

Title: AS AN ACR WDB FREIGHTER WAS XING THE NORTH ATLANTIC ARTCC CALLED TO ASK ABOUT THE COAST-IN POINT. THE FLC GAVE THE CTLR THE PLANNED POINT, NOT THE ACTUAL POINT AND THEN THE CTLR CORRECTED THEM AND INFORMED THEM THAT A RPT OF A POTENTIAL GROSS NAV ERROR WOULD BE MADE BY ATC.
Narrative: XING 52 DEGS N, 40 DEGS W, I GAVE A POS RPT TO GANDER RADIO AND INCLUDED AN INCORRECT FIX. INSTEAD OF CALLING THE COAST IN FIX AS GANDER VOR, I CALLED CYMON. CYMON WAS ON MY FILED ATC CLRNC, BUT GANDER VOR WAS ON MY TRACK MESSAGE NAT 'E.' GANDER RADIO CALLED US VIA SELCAL AND ASKED US TO CONFIRM -- GANDER OR CYMON? AT THIS TIME I STILL THOUGHT THE COAST IN FIX WAS CYMON, BUT I STARTED TO CHK BECAUSE OF GANDER'S LEVEL OF INTEREST. SHORTLY THEREAFTER GANDER RADIO CALLED AGAIN AND SAID THE FIX IS GANDER VOR AND THAT GANDER CTR WAS FILING THE APPROPRIATE RPT. WHEN I ASKED WHAT TYPE OF RPT WAS BEING FILED I WAS TOLD IT WAS AN 'ATC INTERVENTION TO PREVENT A GROSS NAV ERROR.' I HAVE FLOWN MANY ATLANTIC XINGS AND THIS IS THE FIRST TIME I HAVE EVER MADE THIS TYPE OF ERROR. I CONTRIBUTE, TO A LARGE DEG, THE REASON FOR THIS SIT TO FATIGUE. DURING THIS SEQUENCE OF TRIPS, I HAVE HAD NO SCHEDULE TO COUNT ON AND CREW STAFFING IS NOT ADEQUATE ENOUGH TO COVER THE TRIPS SOLD.
