Question For TBC Users

Post by Sunburned_Surveyor »

Hey TBC users! Can anyone recommend a video or tutorial that shows how to combine GNSS vectors and total station vectors as part of a least aquares adjustment?

I can't find a video and can't get it to work with mixed data types. I can perform a least squares adjustment with just GNSS vectors, or a traverse adjustment with just total station vectors, but I can't get a least squares adjustment to use total station vectors.

I know Star*net can run the combination, but I'm a TBC junkie and would like to avoid using Star*net if I can do all of my adjustment in TBC.

Thanks for the help!

As far as I know it won't process total station vectors using least squares method, as you stated TBC wants traverse input format, so Star*Net is the tool for now.

I hope somebody tells me I'm wrong and educates me on how to accomplish this in TBC.

I know this doesn't help but hopefully it will show up on Trimble's radar.

Total station and GNSS data can be adjusted together to some degree. There are a couple TBC Power Hours about integrating data and adjustment which should be of some help.

I've never had a problem, the "vectors" have to be mean angles from measuring rounds. I do GNSS and TS together, and TS only using least squares in TBC all the time.
