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

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 tried this, but I have very high ellipses of trusts.
I do not know if it comes from my observations or common sensors.
