I recently updated my carlson explorer 600+ with survce v 2.04. I'm running it with a Leica tcr805. It seemed to be working fine until last week.
When collecting a set to a new traverse point the data collector computed the new coordinate value incorrectly. I've included a portion of the rw5 file below to illustrate. Notice that the angle turned to point 24 was read as AR354.49040 the reverse was then read AR174.49150. This checks fairly well and is in fact the correct angle. The next line:
--SS,OP20,FP24,AR714.08670,ZE85.56400,SD520.117000,--STA/IPIN
This is where the error seems to occur the AR714.08670 appears to be off by about 40 minutes. This angle was then used to create an incorrect coordinate value of pt 24.
OC,OP24,N 214332.40998,E 449139.13221,EL378.787,--STA/IPIN
The incorrect calculation only seems to occur before the raw data is processed. If I process the data in the explorer or in survcad the correct value is calculated
24 214337.746 449136.309 378.802 STA/IPIN
Fortunatley the problem was discovered with field checks to existing control before staking. It is obviously a potentially huge problem though.
If anyone can see something I'm missing that would explain the error please let me know. For the time being I will have to remove v2.04 until I can confirm that this error will not occur again.
Thanks
Jason
