- Feb 16, 2013Another reason for inaccuracy was not mentioned. The military actually
scrambles the signal a bit to create the inaccuracy. To get full
accuracy you have to know how to properly decrypt the signal. That's
something only the military is intended to have access to.
It's possible to gain a higher level of accuracy by using two GPS
units, one at a fixed, known position. The random error can then be
backed out using this unit as a reference.
