IIRC current military GPS measurements are accurate to within LESS than a
meter (something like 0.1m or 0.2m ... ?).

And with MULTIPLE GPS modules, you CAN get a more accurate reading; a contest
in autonomous robotics (get a robot to pick up a metal disc, fly across a
field with a wall in the middle (all of 2' high), and deposit the disk in a 1m
diameter circular target) I saw on a Discovery or TLS channel show had a
helicopter with some FIVE GPS modules, and a single base station for
reference. The little sucker was able to pinpoint itself, at least in
relation to the base station unit, to within some 1-2 CENTIMETERS, IIRC. <g>
