Okay but with coordinates approximate at few meters it should work right?

It depends on several factors - the better the approximation values, the better the convergence behavior.

And should I treat free stations like reference stations ?

You are the only person who can answer this question. I am just the developer of a piece of software but I am not a member of your project. Please contact your supervisor.

Kind regards

I tried to put them into the "new points" group without coordinates (0 0 0 instead) thinking that it won't influence calculation

Least squares adjustment works only in linear models. Since planar or spatial networks are nonlinear problems, one has to linearize the functional model using a first-order Taylor series. For that reason, appropriate approximation values must be specified by the user. In most cases, [0/0/0] is not a useful choice.

Ok I understand thank you.
How can I indicate to Jag that some points are free stations? I tried to put them into the "new points" group without coordinates (0 0 0 instead) thinking that it won't influence calculation but it seems that I was wrong, so I approximate these coordinates and now it works but really badly.

Here is my project if you want to check : https://www.dropbox.com/s/jmain19nc1r6kzu/omran_2.zip?dl=0

I saw in the leica documentation that normally when you add a station in the tacheomter it add a line in the raw file called bloc code beginning with '41' but it seems that jag3d do not identify this code, do you know something about that?

Code 41 does not represent/indicate a station. It is the code for the point type, e.g., a tree, a landmark, a traffic sign, a gully cover etc. So, code 41 is valid for all lines. (Btw: JAG3D reads the code.)

I know that you can also indicate to jag3d that you add a station with a code '11' like you show me before but I still wanted to know if it is possible to add a bloc code.

Code 11 does not indicate a station, too. It is the point id/name. Like for code 41, 11 is valid for all lines (and required).

In short: There is no specific bloc code in GSI that specify the station. However, bloc codes 81, 82, 83, and 84, 85, 86 have a semantic meaning.
