I have had some of rouge gps coords myself. Ummm.. If you have been having heavy overcast conditions it can cause weaker sat signamls to disappear altogether .
Which make and model GPSr are you using?
I'll do some digging wround the internet and see if I can come up with some remedies for poor signal

Okay BoBer.. Did some digging.. not really much to help with GPS reception other than
A) use an external GPSr antenna if possible
B) relocate the GPSr to reduce interference from other objects
C) wait for better weather LOL

YEah I have had data jump on me just like that before. I'd send pic but that just gonna take tooo long LOL

I've seen data like that when i have a real low amount of satellites. Vistumbler uses a checksum that is in every gps string to determine if the gps information is corrupt, but you still see some weird data like this with a low number of sats.

Andrew is correct... The more sats, the more accurate the fix.. this goes for all GPSr's... The first image you sent, apparantly you had enough of a signal/sat loss that you had one set of coords zero out at position N00.0000 and E000.0000 .
