Lost GPS tracking

My family and I are currently on Magic, and they have lost GPS tracking of the boat. There are no updates on our current location and the locator maps have us incorrectly positioned. We always look forward to watching where we are, but not this time :(

You should be able to recalibrate once you are in port. GPS can be flaky depending on the type, age, and maps of the unit. Early units required recalibration whenever you went more than 600 miles from a starting point. Early units also selected the nearest satellites to get the information, whereas, more recent have gone to selecting the best connection. (Sort of like looking for a WiFi with a phone. there may be a nearby WiFi but the signal is weak, while one a little further away will have a stronger signal.) And the satellites are turned off at random intervals for software updates and so on. Most of the Satellites are actually about 25 years old and they do need updates every so often.

 

So. when you reach the next port (or you can try to do it at sea) turn off the unit. And recalibrate. You might even see if a navigation officer might want to help. (That way you can actually meet the Navigator or Staff Captain.)
