Carlson collector problems
I have used Carlson for many years and I have never seen this problem before. Today I set up the instrument on two points I Gps'd earlier. Turned another point with robot then occupied it. Shot BS and checked .02 hz and .003v started to topo then went to turn another point up with "set collection" now all of a sudden my backsight was getting.08 v, we then checked all the heights and levels and shot again still 8 hundreths off. I look in rw5 and the coordinates were totally different from what was stored in crd file. Actually they were 465' away from correct coordinate to the wrong ones. Somehow it is flipping the azimuth. This is second time in a row this has happened on a topo job. It also changed cords for my first GPS point that I never occupied but only backsighted.
Somehow the azimuth is flipping 180°
I have no clue how this is happening..
The coordinates are correct in my rw5 but wrong in the crd/points list.?
*Edited to show how different coordinates were.
This is a known issue I have always had. When you setup on a known point and the BS derives an error, when you store your setup, it will adjust the occupied coordinate. I found this out on a highway job about 13-15 years ago (time flies) Surprised it's still doing it.
Are you using version 6? I have heard of some bugs w/the new version in set collection.
Happened to me two weeks ago, points in the middle of the set, exactly 180° off. I created a polyline from the first to last point, mirrored that line and moved them 1 point at a time. Having done the work in the field I figured out a way to fix it in the office. If you were not in on both ends of the problem it would be hell to figure out a easy fix. Been using a older version of Carlson in an old Explorer for 6 months now since my SMI/HP 48 mysteriously disappeared.

Sounds like you should start your search for that HP 48 amongst those you know using Carlson.
