Have one Reach RS and a correction service, want to measure GCPs in real time

Hi Romi
If you take a look at this picture

And info about DGNSS, and how accurat this type of correction is
http://www.novatel.com/an-introduction-to-gnss/chapter-5-resolving-errors/gnss-data-post-processing/

You see that, at best you get around 50cm accuracy and the accuracy of the correction decreases as the distance to the station increases.

Here is a picture of basic setup. You see i get a dropdown menu and are able to select mountpoints


You might change the RTCM version as well.
