All 3 GPS receivers on my bridge lost position simultaneously, and then began tracking again about 30 minutes later. Oddly enough, my GNSS receiver (GPS and GLONASS) worked perfectly and did not lose position. Any thoughts on this? > > Jeremy Well, for sure the GPS in your area was not selectively turned off. We have it on good authority that GPS has never, ever, been turned off.... No doubt there was some malfunction on all three GPS receivers at the same time on your ship and a thorough investigation will track it down. Geoffrey Kolbe
