Hallo Sean!   
      
    SD> I've been hearing rumors that "they" may lift one of the GPS   
    SD> filters to make it more accurate than it is now...not sure if I   
    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.
