Charles Trimble

If you were hiking, sailing, you're a real outdoor enthusiast, these were the first kind of little... set little fairly affordable receivers you could have by the early 90s that was the first place you could get them.

And yeah, and they were going to civilian receiver makers there's a guy called Charlie Trimble they were going to his company and and buying civilian receivers off them for the military and sending them to Iraq.

And I think it's sort of one of the things that people don't realize is you think in retrospect that the U.S. Department of Defense, and especially the Air Force, which was sort of kind of most responsible for it, realized what they had, realized that this was so useful.

But it's quite a recurring refrain for some time, deep into the 90s at least, that the Department of Defense doesn't quite seem, I'm sure somebody will call up and complain about this, but like to hear the GPS sort of elders say, they didn't, you know, he said, there's this guy called him Gaylord Green, who's one of the fathers of GPS.
