glorkar Posted July 23, 2010 Share Posted July 23, 2010 I've been finding a lot of GPS benchmark disks. Most of them are from 1999 and 2000. Today I found one from 1993. It got me wondering when the first ones were monumented. Anybody know? Quote Link to comment

It got me wondering when the first ones were monumented. Anybody know? It was different for each State and County. We built our first GPS Network in 91 & 92. The State followed in our area after that. It was all based on NGS setting the HARN Network. Quote Link to comment
