When was gps first used?
Around 19591959? Not likely since GPS didn't exist then.The first GPS satellite was launched from Vandenberg Air Force Base on February 22, 1978. However, it wasn't until the mid-1980s that commercial GPS equipment appeared on the market.
When did the GPS become fully functional?
The first series of GPS satellites was called Block 1 and was only used for feasibilty demonstration until the operational Block 2 satellites were launched. The third Block 2 GPS satellite was launched on 18th August 1989 and as you need atleast 3 visible satellites for a fix that is about when GPS started as a working system. Coverage was extremely sporadic at first as there was rarely three or more satellites in view until much more of the constelation was in orbit a few years later. In about 1991-2 I used an early GPS receiver, it was roughy an 18 inch cube including the CRT screen, weighed about 100lbs or so and needed a large (by modern standards) external antenna. Due to the low number of satellites in orbit it only gave a fix for a couple of hours, roughly twice a day.

GPS is the successor to several earlier systems of measuring position. Loran in WWII, then Radar, Navstar, and so on. GPS is such a complex system that it is doubtful if any one person can understand all of it.
