Survey Pro glitch???
Long story hopefully as short as possible.
Yesterday I used the latest Survey Pro software in Ranger 3 with a Trimble S5 1″ robot to do a 2 point resection. I ran 3 sets of angles to both points on a site I have great control on with elevations run with a digital level. The residuals came back 0.00 HZ and 0.01 VZ (one point was about 700′ away so expected a small vert error). With Survey Pro after the resection it automatically sets your backsite to a roving target and I don’t like this so I always do a new setup on the point I just established and set it to a Fixed backsite. My check to the backsite came back 0.00 HZ and 0.24 vert. I checked the 2nd (closer) point I used as a resection point and it was off 0.06 vert. Ran the resection again checking everything from measure ups to prism type etc and even added in another point. Residuals 0.00 HZ and 0.00 vert. Backsite check 0.24′ vert. Checked another control point 0.11 vert. Did a remote elevation from that control point (direct and reverse) then staked out to my resection points and they were all off, this time I noticed the further they were away the bigger the error. Figured my robots vertical has gone south so loaded it up and shipped it off to to fixed. Back to the office to get the S6 2″. Set on same resection point and checked the BS for 0.04 vert which I thought was reasonable considering it was 700’+. Then checked the last point I had staked Thursday and was 0.02 (also a longer shot). Ran with that and staked about 800′ of curb and checked into a different control point 0.20 vert. Checked into a point I staked the week before near that CP 0.18’….WTF is happening here???? Checked my BS for you guessed it 0.24 vert!!! Turned everything off and started again and the BS checked for 0.04, then checked all the points I just staked and they were all off 0.07 to 0.15′ vert. Fixed all those points then checked into the point from Thursday 0.02 again. I am totally baffled now! In my opinion it can only be the Survey Pro software giving me bad data. I am going to copy all my projects from my main DC to my backup and see what happens. Has anyone ever seen this happen and if so did you ever come to any resolution?
Thanks for reading!
