RE: [Paddlewise] Oddities of GPS

Hey Alex,

Three possibilities come to mind:

1. What part of the world were you in? If it's a "hotspot," might the US military, who run the GPS system, be scrambling the signals available to civilian GPS so as not to assist their opponents?

2. Could you or someone else have accidently reset the map datumn in your unit? That's effectly resetting the zero points for the x any axes or lat and long, and might account for the weirdness, especially if a "custom user" datumn were entered.

3. Solar flares scrambling the signals?

Cheers,

Philip
