OPUS is easier. It took me about 45 minutes (because I forgot how to do it). Next time won't be so bad (if I don't wait two years again). However, I used about 6 CORS stations instead of three and had EXCELLENT results with processing the independent vectors and meaning the values (what OPUS does).
The only issue I have, and I cannot tell you why, is that when I selected, after I was through processing the baselines independently, all of the base lines, and I processed, it only processed to one of the CORS stations and not all and mean the values (which is what I did independently I just didn't save the baseline processing).
Any thoughts on why TBC wouldn't process all the lines and mean the answer by itself?

Ohhhhhh, you wanted the multiple baseline processer?? I bet they have a license for that, just send them a check. :-X
Just a guess...maybe you have it set to pick one baseline at a time. Try holding the CNTRL key while you select to add each vector to the set of data to be resolved.

I bought the "big boy" package so I already have it (but not sure how to use it). 🙂

I did that exact thing and viewed the six baseline answers it generated. Then, after I stored/saved the baseline processing, I selected the baselines and generated a 90 page report, whereby it notes the slight differences in each of the baselines as processed. The coordinate that it is showing for the processed point, is the same value as one of the values from only one CORS. That being said, it's not close to the middle of the answers either as it was on the high side (I noted 0.015' X&Y from high to low and 0.05' in the Z).
I have no idea why it didn't mean them.

Did you designate all of the CORS positions as control quality?
Go to the Project Settings menu and click on Computations; make sure it is set to Weighted Mean Of Like (or All) Observations.
This is only available after a certain version of TBC, maybe 2.70.
You need to do an adjustment. Pick the stations you wish to hold as adjustment points and check the box. So far you've just got a single solution.
Did a "Roll Your Own" OPUS today (TBC)>Kris
If (or when) the government opens back up check out the Corbin training site for NS and find out when the OPUS project managers training will resume. Multiple stations and processing (for free!)
I know that it's not helpful now, but it may be eventually!

Yes. I don't know what else to make this thing act right with.
Didn't know about that one. Definatley will give it a look.

No. It processed all of the baselines at once and showed their answers in the report. It kept the last answer as the final answer.
Yes, you processed the baselines, but did you preform an adjustment after the processing. Under survey one of the pull down options is process baselines, then there is an option for adjust network. This will allow you to pick fixed stations and will adjust your control point to the baselines from the held stations.

Badass! That worked like a champ after I changed the setting. Totally recomputed the point to 0.0005 of what I had calculated in the first place in the N&E and 0.01' in the Z.
Excellent board!!!!!!!

Mike, Lee D above had me change a setting and it worked like I remember it working in TGO.
In this case, the network was CORS and held as fixed as I changed the quality of all CORS stations into CONTROL. Then, once I changed the setting Lee had, it processed all baselines and then gave a mean of those values. I'm sure the differences I found were in pure round off.
Excellent Surveying Thread!!!!!!! I'm archiving this for the next time I get a new computer. This is one of those settings that is a MUST if you're gonna roll your own. 🙂
Did a "Roll Your Own" OPUS today (TBC) Update
After OPUS came back up today, I submitted my file and the OPUS solution using three CORS agreed with my "Roll Your Own" solution, using 6 CORS, within 0.002' in the N&E and 0.01' in the Ortho.
Color me happy.
Why not create a template saving all your settings? Keep a copy and upload to your new computer and you're ready to roll.
I suppose you're right and I use tbc templates but when I swapped from tgo to tbc, I had to reinvent the wheel.
