I was using Terraflex with our R2 and came across an issue. I recorded several points that I had known elevations for from previous surveys done using higher level equipment. I was getting 3 in. vertical and horizontal accuracy using a local VRS configuration in the NAD83 CORS 96 datum (northern Ohio). When I got back to the office, I converted the HAE values I recorded to MSL. All of these elevations are exactly 4.5' lower than the known elevations I have. 4.5' is also the number I have in for the antenna height. Its like the software is performing the offset math twice...
Has anyone else encountered a glitch like this? Or is it not a glitch and I'm doing something wrong along the way?
Thanks in advance!
