Looking for technical details of RMT target: What is the IR carrier signal? (Trimble/Geodimeter)
I haven't looked at that one for a year or so, but if the 606/604 IR frequencies are not in there, I'm fairly sure I have a slightly different/older version that stated the frequency. She's been a long road, but when 4 years ago I got my Geodimeter 650 ex USA (from someone who posted a couple of times on this Forum), then acquired (at high price, the RMT, ex USA also) and saw that thing spin and track, well ... Added my own homebrew radios ... SurvCE ... .RTK is the king, and we try and use it exclusively, but robotic TS is more satisfying.
Better than gold!
That's going to be a good evenings reading! Well done.
That misalignment is more than you would expect, but it isn't really going to make any difference to the measured distance UNLESS you are getting a very weak signal due to range or obstructions/atmosphere. As long as the instrument locks on OK there shouldn't be a problem. In my experience the 600 series never reached the range abilities for finding the target that the 4400 used to have - generally the 4400 used to get at least an extra 50 metres.
Yep. The GDM manual does say (from memory) that for accurate distance measurement, one of the 360 degree RMT mini prisms must be aligned to the instrument. (We wont be doing that for each topo shot, and probably wont check that when doing control). So presumably with a 300mm tracker misalignment at 200m, if you rotated the RMT it would give different distance readings. We have 1 arc second GDM and 5600's, so for angle that's 1mm at 206m, so maybe with a 300mm tracker misalignment that's going to "add" maybe 5mm to that.
Oscilloscope ordered and I have to stay off my knee for a while according to the doc, so, sitting by the lake learning electronics ... This is going to be interesting
