I've seen ads for single board GPS units.  Sounds like a great
navigation aid might get a whole lot cheaper and perhaps within 
reach of my financial, ahem, capabilities.  

Does anyone know if I could get around 1 cm repeatibility if I
averaged the signal?  I theorize the intentionally added error 
is randomly dispersed about zero if taken over a long enough period.
Note that I want repeatibility, not accuracy, in the centimeters.

Anyone got any ideas about how long that period would be?  Pardon me
if this has already been thoroughly discussed in this group.  

Pointers to further info would be appreciated.  Thanks.
