GPS satellites "dither" the information they transmit to intentionally
uncertainty. That keeps our enemies from accurately flying GPS-guided
at us! Military users can overcome this dithering, thus gaining better
However, if you use "differential GPS", by keeping the GPS receiver
you can average out the dithering and get military accuracy. The
that tactical military advantage is only gained if you can get highly
readings when you are moving (whether it is in a jeep on in a missile).
GPS is commonly used by survey teams to very accurately locate things
mountains, which don't tend to move very much.
