Yo All!
I'm still working on the centi-meter accuracy thing. Base/rover mode,
not free range mode. See attached for a scatter plot. CEP(50) of
0.007m, CEP(95) of 0.027m!
I had to replace the function to calculate the earth distance between
two points with a better function: Vincenty's Formula. Supposed to
be accuarate to 1mm.
Of course the numbers are now so small that gnuplot gets confused, so more
work to do.
