@rj-schneider My first thought as well
Since the time the Internet first arrived, it has evolved to the point where you learn every meaning has changed to either the name of a rock n’ roll band, or some company attempting to market their products.
Take Kestrel Instruments, for an example. I don’t know what instruments these Kestrels play… Perhaps some kind of medieval revival would be appropriate. If not, these birds should sue for copyright infringement.
Historic Boundaries and Conservation EffortsHave you tried different points for the resection and checking the fixed (control) point from a different setup to see if the 12 mm error is replicated?
Also, how good are your resection results after the service (calibration) compared to before?
@minbarwinkle I sent back the kit forthem to do it properly and got a replacement TS16 back and did the same face 1/face 2 measurements (same checks) on it and got 7mm error in 150m – what I believe not too bad for a 5″ kit. This also means, that my 1″ total station should get at least the same result if not better…
I’ve tried different resections to do the same checks, however I was checking the calibration of the kit with these checks, not where I am positioned on the site with each resections as the retro targets are not 0mm perfect (there is always a few mm error in resections). Luckily the subcontractor’s engineer is a friend of mine so we keep checking each other’s setting out to make sure we are on the same page, usually we are in 5-6mm tops – what I believe is the difference between the total stations/resections, etc.
This also means, that my 1″ total station should get at least the same result if not better…
Same? Yes, probably. Better? Probably not. Generally, the instrument contributes only a small fraction of the error in the instrument – tribrach – tripod – setup – target prism glass – target rod/tripod centering system.
@gk88 I am using a 1″ Geomax Zoom 95 with the X-Pad software and I do reflectorless resections every day from “stickers ” set by myself before the project started. The distances to the targets are 160m to 250m. I always get the residuals less than 1mm for the distance and less than 2″ for angles. Re-staking points done from previous setups always yield “perfect” results , 1 to 3mm and this is done using a Leica 360 prism.
little update… got back my kit again and “surprisingly” much less error I am getting… on 100 meters I have 1mm (!!!!!) error on the face 2 measurement (face 1 was obviously zero). I wish they cared at the first time.
