TBC help?

First off... Make sure your point numbers in the terrestrial job file and the GPS file are numbered identically.

Set the quality of your GPS points to control and the terrestrial points to unknown. That should get you running.

I would suggest Michael McInnis of System Dividends if you decide to seek training. He will show you what works and what doesn't and get you working and making money with your investment.

For what it's with, and don't quote me or do what i say..... but OPUS will not recognize files converted from TBC at the moment....Something with the software. Just had an OPUS Projects Manager class with our NGS advisor and i "believe" thats what he said. Don't process it, just transfer the *.00* file and use TEQC......

I might have said it wrong, but i'm sure you'll see comments from our seniors........

StarNet is more flexible but TBC works well with Trimble sensors. You just need to develop your field and office procedures to work efficiently with TBC.

I would invest in at least one or two days of training on TBC per year.

I would also suggest using data transfer to download your job. Checking and editing the raw data is a lot easier to do in an *.dc file than it is in TBC.

FWIW, I imported the files directly from my receiver. Then I used the external processing tab to send the points to OPUS. They came back with the OPUS report and an xml file. I was able to import the xml file (after deleting the raw files) and the points came in properly. I check the OPUS report vs the xml and everything checks... so far.

Whether or not training is worth the price depends on the instructor. I have had training that was ultra-informative and brought me forward by leaps and bounds. On the other hand I have had training that was an utter waste of time/money/money (what I paid and lost in billings).

That said, the tutorials that accompany TBC are great resources.

Be careful importing the XML for OPUS solutions, it used to not import correctly. This issue hasn't popped up on me again, but mess up once and I am forever skeptical (meaning I check). Verify that your global coordinate matches the OPUS report.

Set your project up defining the coordinate system you wish to generate output points from. Import your TS data, when you do be sure to select that you want to keep your TBC project coordinate system definition.

Select a pair of points that represent the same point and go to CAD, merge points. Do this with all similar points. You will now get error flags because of the conflicting coordinate values.

Then navigate to the merged point in project explorer. Locate the assumed coordinate value under the point drop-down and delete it. F4 to recalculate. Flags should disappear if values are within defined tolerances.

I don't know what I just did, but what you said worked. Thank you!

How do I set the quality of the GPS points? They are currently saying Local. I have right clicked and been to properties, but can't find where to change it. Also, the OPUS point are grid positions, so I don't want to hold hold them both - is there a way I can hold one fixed the other just for an azimuth?

You told the program that the points are the same, then removed the "wrong/assumed" coordinate allowing it to use the OPUS coordinate for calculations.

Pay attention to the Merge dialog, it allows you to control which point Name is kept. You're welcome!

You needn't delete your GNSS observations to import and use OPUS data. Be very careful to check which coordinate values are being used and/or are influencing your calculations. When importing .T02 files the "here" coordinate comes in to serve as a starting point. Deleting the raw data may not necessarily delete the "here" coordinate. You set the order of control on coordinates by right-clicking on the coordinate values under the point in project explorer.

There should be a box next to the coordinate or point that should a cyan triangle or a survey tripod or a ?.

That is where you choose. Just set one as control and one as survey. You should go through the trimble supplied tutorials too.

You will learn fast that it is far easier to have all of project settings correct before you start importing data to a project.

I just finished two days of TBC training and we are using the latest version (yellow icon).

It seems to me you bring up the project explorer and find the point in the list of points.

Expand the point, the OPUS point imported will be "office entered." Change that one to control in properties.

TBC Tutorials

This is where mine are found

i am pretty sure that it automatically creates itself when you run the install.

All the data for completing the tutorials are in those folders.
Very useful for a first time user.

Enjoy

Another way to get some useful info is searching You Tube for your version of TBC. A lot of it is in different languages, but you will find many basics there to get you started.
