Hi,
I’m new here, and to surveying. I am trying a new reach 2+
I have tried 2 different correction services, and the GPS is in an open area, but I only get 10cm accuracy. Any tips?
Thanks
Tristan

Hi Tristan,
Welcome to our community forum!
As I see on your screenshot, the precision is 0.010 m, which is 1 cm
I’ll see myself out
If I setup my own base station, and I’m within a 100 m or so, will accuracy increase further? Or is 1cm the general limit
Hi there,
‘1 cm’* is the best you will get. Using a base/rover combination will not change that.
If you need smaller values (mm), consider the use of a total ($$$) station, but do not skip the entry of the values that account for the correction of curvature and refraction. It should then give you measurements with a 3mm cadastral confidence level (up to a couple of hundred meters).

PS: Please keep in mind that the values displayed are *1 sigma (68.3%). If you need a higher level of confidence (95.5 or 99.7%), you need to multiply by 2 or 3 respectively.
(This basically applies to all GNSS receivers available.)
Thanks mate,
Sorry, I don’t get the reference to “a total ($$$) station”?
Hi there,
Total Stations are far more expensive than GNSS receivers. That was the point.
Cheers
