My condolences, I can't imagine how hard it would be to deal with that, that's really tough.

We just got our Topcon GLS scanner back fresh from calibration, I levelled it, rotated it 90 degrees and it was out over 38 arcseconds, the calibratio...

Little bit more info on RepairRinex, it removes observations that would cause the RINEX file to be rejected, eg, it removes satellites with incomplete...

Hmm, a center leg with foot, that's a relatively simple addition, so everything else becomes stabilizing outriggers. That's probably worth trying befo...

Some more tests this morning, I found a parasol umbrella, with spring and rubber clamp, this alone was sufficient to eliminate the resonance. It loo...

We've been using SALSA for two years, the results are excellent. It gets a little slow once you hit 18,000 observations, we've included GPS vectors &...

Scan completed after releasing leg clips, these were causing legs to bow due to legs bending past the clips restraining angle.

The first lot of photographs, when we were having trouble with vibration. Last image with arrow, showing leg clips that hold legs at an angle.

Thanks @OleManRiver appreciated, testing will help us understand if the tripod is viable. We have some very interesting results from our first test to...

This is what motivated us to design the new tripod, the noise in the background is a conveyor, there's no ground movement, there's a breeze, we've ten...

@RobertUSA The SX12 has a field calibration routine for level, when we first level the instrument, we level it within an arcsecond, then rotate it 36...

@OleManRiver , @lukenz Thanks for your encouragement 👍

@OleManRiver 👍😀<div>Thinking about making a couple of prism holders that can be installed in the main shaft of the tripod, so th...

@OleManRiver This presentation is interesting, on the NGS site, I only see the optical theodolite method, but this presentation mentions approval of ...

Going to test it this weekend. So far, when scanning with the SX12, we've only been able to use quality timber tripods, even brand name fiberglass m...

I am considering incorporating a nodal prism in an aluminimum bracket beneath the head, on top of the 70mm shaft. This might assist to transfer level...

In Australia, I haven't been to the US yet, something worth considering when I do, my daughter's our surveyor, she has an appreciation for history, ha...

All optics in those days, I can imagine how careful you'd have to be not to wobble the tower while your co-workers looking through the eye piece, lini...

That guy on stilts cracks me up, practise makes perfect as they say! 🤣
