QuoteTime for refund from Sparkfun for selling you and old revision?I wish . . . I bought mine like ~2 months ago if I remember right . . .I'll probably just buy several and try them all out. It might take a month before I report back, however.

Madsci,Are you following the DIYdrone discussions about the U-Blox? Particularly this one:http://diydrones.com/forum/topics/for-gs407-ublox5-gps-4hz-diyThey do mention a new GPS unit that may be even better. Rick Brooks
Lol, that's the one I have and linked to in my last post. I love it.
the US stopped the GPS reduction in accuracy like 10 years ago. DGPS made GPS so accurate even with the added intentional noise that it didn't matter any more.
when is Europe ever going to get their 'better' GPS system working? I hear you guys still haven't figured it out
Before we go around bashing the US, and false spreading rumors, the US stopped the GPS reduction in accuracy like 10 years ago. DGPS made GPS so accurate even with the added intentional noise that it didn't matter any more.
Some of the expense of the DIY drones approved Ublox5 is it's super awesome helix antenna. And either you have to spend more on an antenna for the GPSbee, or it has some crummy on chip antenna that wouldn't compare to the quality helix.
And other units may be recommended by 'some' DIY drone guys, the Ublox5 is the "officially recommended" and official Ardupilot GPS. The Venus taught me my lesson, I'm not going to try to save $20 here or there, when there's a whole relevant community recommending a single unit. Now I wish Sparkfun would rewrite their GPS buying guide with actually tested results, not just sum up features on paper.
My two boards had badly mismatched inputs--2 dB return loss. Was able to tune with 5pF capacitor in shunt. Sensitivity is poor, but works OK with active antenna when outside. Takes a very long time to first fix when signal is weak.
I used this onehttp://www.sparkfun.com/commerce/product_info.php?products_id=177But still, I remember it reporting good signal strengths, just crappy calculations and long fix. The Ublox really does blow me away.
