A-posteriori uncertainty of the azimut

Hello.
How to calculate the a-posteriori uncertainty of the azimut (exactly azimut!) for the line between 2 determined (adjusted) points? (There are no direct measurements between these points).

A-posteriori uncertainty of the azimut

Hello,

its on your own. You can export the fully populated variance-covaraince-matrix of the adjusted points. By applying the propagation of uncertainty, you can derive the uncertainty of the azimuth angle (or any other parameter).

Kind regards
Micha
