20 years ago, the gps system achieved full operational capability.

A short time later, I got my first handheld receiver, a very basic unit = eagle explorer.. What a change 20 years makes, much better maps on reciver, no S.A signal for more accurate position, longer battery life.

Good job to all those involved, in making gps available.
