### 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.

• 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.
