    This came over the aviation channels....

    I contacted U.S. Coast Guard Navigation Center and made them aware and they are now going to send out the information to there Sector offices. But they could not direct me to any online notices. Perhaps the sector will post something. Until they do, be careful relying on GPS during these times.

    GPS reception may be unavailable or unreliable over a large portion of the southeastern states and the Caribbean during offshore military exercises scheduled between January 16 and 24.

    That would be a bit of a bummer if you had planned a trip in unfamiliar waters during the outage. Break out the paper charts??? Yikes :)

    What about cars? The region for the 50’AGL overlaps land. If boats are affected at sea level, then cars too. Granted, most phones use a combination of gps, triangulation of cell towers, and known wifi hotspots, to determine location, but standard car gps would not. and what are we talking about, instead of 1 or 10’ accuracy you get 50, or 500, or just signal goes away?

    This is informational only. I have no idea as to the accuracy of the specifics...I would caution anyone relying on GPS during these times to be aware of there surroundings.

    I guess if you're driving be wary around sand bars and areas known for shoaling.

    Other bars are OK if they serve a good gin and tonic. :cool:

    Geez, from NC all the way around Florida to Alabama. That's a huge area and if it does affect all GPS, there are going to be a lot of drivers heading to Florida and ending up in the mountains of Tennessee!
