I think you are correct - there seems to be no support for NAD83(HARN) in the Trimble Coordinate System Database. If were to be needing those numbers ...

@timd1971 It is realtime - it turns or zooms with the instrument It is as accurate as the instrument - SX12 can be +/-0.5mm Haven't really found any l...

#NiceVid Those who have not used a new generation receiver like the R12 should get out and try one. They genuinely are a big improvement on what we ha...

Around here (New Zealand), failing any documentation that shows the closure of the alley, you would be claiming Adverse possession. While the timefra...

I see you are using SP-85 receivers. Nothing wrong with that. But they are previous generation units - nowhere near as good as an R12 or similar unde...

Define 'fixed' It can be just that the software is able to repeatedly calculate the same position a number of times a number of ways. So for example ...

But you might be able to minimise the number and their effects

Prevent? You can't!

With time dependent transformations (like ITRF) the epoch of the coordinate realisation is important. You may be seeing 'current epoch' values, and co...

The usual Trimble firmware procedure is to connect to the receiver and use Trimble Installation Manager. That checks the hardware capabilities and li...

> I learned about lat/long being the “true” measured positions, and grid coordinates are the calc’d ones. True, but only up to a point. If you cha...

I think it unfair to blame Trimble for decisions made by your telecoms provider to close down 3G Trimble had NO say in that decision. 3G still works ...

If cost is not an option, you really want a Trimble R12.They are just simply streets ahead of anything that came before - especially under canopy
