Local Cartesian System and Earth`s curvature

Hello,

Why, in this case, do you not take into account the vertical deflections from the local plane of points A, B and M when adjusting networks 30m, 60m ... 40000m?

I'm not sure, what you are meaning. You are talking about the Evaluation of Compatibility among Network Adjustment Software, right? The used JAG3D projects are available. In all projects, an ellipsoidal Earth model with local Cartesian coordinates is used, see the screenshot below. If the option "local ellipsoidal system" is selected, the tilt is known by definition.

Kind regards
Micha
