Hej luked,

I am wondering how these numbers were obtained. Is there a feature within JAG3D that will help with this or was there a particular formula that you used?

No. You have to provide such information. You can try combining the stations one after the other — in other words, sequentially. You can also use a standard Helmert transformation to obtain an initial guess. For the given example network, zero values work well for both angles, but in a larger network this will certainly not work as well, and the values should be more "representative" than just zero.

Kind regards
Micha
