Course content

Geometry of the reference ellipsoid, datum, geoid. Conformal Gaussian map projection of the ellipsoid. Satellite geodesy (GNSS/GPS), centeral GNSS errors and ambiguity in phase observation. Transformation of GNSS satellite baslelines to a map projection (plane). Estimation of coordinates and heights by least squares adjustment. Reliability analyses of observations and networks.

Learning outcome

Knowledge:

The students should have knowledge of:

  • Transformation of GNSS baselines to observations in the map projection (plane) and national vertical datum.
  • Geometry of the reference ellipsoid, and calculation of coordinates on the reference ellipsoid.
  • The general conformal map projection of the ellipsoid onto the plane
  • Central sources of errors when doing observations with GNSS (GPS).
  • Estimation of coordinates and heights, quality control of observations and reliability analysis of geodetic networks.
  • Recent topics in satellite geodesy

Skills:

The students are able to:

  • Carry out calculations on the ellipsoid by using the two geodetic main tasks
  • Calculate coordinates in the map projection (plane) from GNSS observations
  • Carry out and understand reliability tests as described in the Norwegian Geodata standard issued by the Norwegian Mapping Authority
  • Understand and mitigate multipath, ionospheric and tropospheric errors on GNSS signals and ambiguity in phase observations
  • Understand recent topics in satellite geodesy

General competence:

The candidate can:

  • Understand the theoretical basis for calculations on the ellipsoid and on the map projection (plane)
  • Understand the theoretical basis for calculations and reliability analysis of coordinates and heights
  • Advanced understanding of GNSS and satellite geodesy (recent satellite geodesy missions)
  • Understand and use professional terminology within the discipline
  • Work independently and in team and take the necessary initiatives
  • Identify common fields between this discipline and other professional disciplines and be open for inter disciplinary approach and cooperation.

Learning methods and activities

Lectures. Computations and laboratory excersises. Programming. Use of existing software.

Compulsory assignments

  • Exercises

Further on evaluation

Written exam accounts for 70% of the grade and project work accounts for 30% of the grade. Each part of the assessment will be awarded a letter grade, which is then combined into a single final grade for the course. Obligatory exercises must be approved in order to attend the exam. If there is a re-sit examination, the examination form may be changed from written to oral.

Specific conditions

Compulsory activities from previous semester may be approved by the department.

Course materials

Hofmann-Wellenhof et al: "GNSS". Compendia published at the department.
