Hallo Sean!

 SD> believe it.

As we speak, the USB one I have is showing;

Long Err  (XDOP, EPX):  0.71, +/-  2.7 m
Lat Err   (YDOP, EPY):  2.66, +/- 10.0 m
Alt Err   (VDOP, EPV):  3.80, +/-  9.2 m
2D Err    (HDOP, CEP):  2.80, +/- 10.3 m
3D Err    (PDOP, SEP):  4.80, +/- 13.8 m
Time Err  (TDOP):       3.09
Geo Err   (GDOP):       5.55    

Those numbers are a bit higher than usual but it is cloudy and raining so that 
always has a negative impact on GPS.  On the new one I plan to add an active 
antenna so that should improve things, not to mention as the extra IO the 
reciever will have access to.  Once I get that working I plan to take the USB 
apart and see what is REALLY going on in there.  I might be able to hack it and 
improve it's output if it is a simple matter of rewiring it to a better 
interface to get things like PPS working.

 SD> Always fun!  I am working on setting up a Linux box to replace
 SD> the Windows box in my ham shack...

Always an excellent plan.

Het leven is goed,
Maurice
