Course content

- Introduction/repetition of linear algebra
- Least squares adjustment (the parameter method)
- Development og error equations for  leveoobservatio types levelling, total station, GNSS baseline, GNSS point observation
- Weight functions for the same observation types as above
- The theory behind multiple t-test, Chi-square test, F-test, confidence intervals, inner and outer reliability
- Adjustment computations by means of the most common Norwegian softwares and corresponding Norwegian standards
- Additional parameters in least squares adjustment (scale, rotation and deflection of the vertical)
- Simulation and planning of reference point measurement

Course materials

- Since the course relies heavily on Norwegian professional standards and the Norwegian variant of least squares adjustment and associated statistical tests, all the written course material is also in Norwegian.
