Maybe.

I'm sorry, but without any data, nobody will give you a right answer.

yes, it is.

"Maybe, you have a wrong configuration, i.e. you haven't divided the directions into separat groups (each group represents a set of directions that has one unknown orientation). Maybe, your stochastic model is not correct. Maybe, there are some outliers... etc."

Maybe.

Thanks for your answer !

Bulk calculation is to perform a calculation for several theodolites

So, it is just the combination of sensors during the adjustment process, isn't it?

I tried this, but I have very high ellipses of trusts.

Bulk calculation is to perform a calculation for several theodolites with common sensors that will stabilize the topographic network and allow a better determination of the coordinates of all the sensors.

"Okay, you have to import the observation data from both instruments. Moreover, you have to import/define (approximation) coordinates of the reference points and the new point."

I do not know if it comes from my observations or common sensors.

I have questions about group compensation for JAG3D, more precisely on block calculation.

I'm sorry, but I don't know the term block calculation. Can you explain the term?

In fact I have two theodolites and I would like to calculate them together.
