I am using a single baseline RTN with Trimble Access. My question is can I do a adjustment in Carlson SurvNet?
I have been using the .dc file for the input file. SurvNet is saying there is no control point and is asking for two control points or one point and a azimuth.
Any input is appreciated.

I have very limited experience with RTN's and with SurvNet. Most of my adjusting experience is with StarNet, some with LGO. My RTN experience is with Oregon's system, which is driven by Leica's Spidernet.

I'm certain you will be able to after you fix the position of the virtual reference station in your data.

A little story about my experience with SurvNet. I was using Carlson 2012 (in late 2011) and decided to try it out. Among the things I want to try was geoid modelling. But SurvNet only had Geoid06 loaded. No Geoid09. So I emailed Carlson, and got an email back that they needed a little time. In a couple of days they sent along a patch that added Geoid09 as nice as you please. But the point is that Carlson 2012 didn't have Geoid09, 3 years on, and Carlson didn't even have a solution at their fingertips. Was I really the first person in 3 years to notice this? I don't think that the user base for SurvNet is very large, hence the lack of responses to you question. And more's the pity. I found that it mimics StarNet Pro pretty well.

I have the same question. With the Leica system (Master Auxiliary) you should be able to do least squares adjustments by fixing the location of the master auxiliary, because the raw data would include vectors from the MA.

With VRS, I am less sure how this works. Additionally, the VRS location changes and moves if there is an interruption of the network communication.

I tried loading this into StarNet, but can these be used in an adjustment the same way as a standalone base?

As immense as the help manual is for Carlson SurvNet, the actual instructions on how to set the control appear to be limited, and very hard to find. I've only done it a couple of times, and never with a .dc file, but the gist of it is that you may need to manually enter your control coordinates at the beginning of your raw data file before processing, using the raw file editor.
