GPS and Geodesy
About
About the course
Course content
Geometry of the reference ellipsoid, datum, geoid. Conformal Gaussian map projection of the ellipsoid. Satellite geodesy (GNSS/GPS), GNSS measurement errors and phase ambiguity. Transformation of GNSS satellite baselines to a map projection (plane). Estimation of GNSS coordinates and heights by least squares adjustment. Reliability analyses of GNSS 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
- GNSS measurement error sources and phase ambiguity.
- Estimation of GNSS coordinates and heights, quality control of observations and reliability analysis of geodetic networks.
Skills:
The students are able to:
- 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 GNSS phase observations
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 GNSS coordinates and heights
- Advanced understanding of GNSS and satellite geodesy
- 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.
Programming, coding and implementation for the project work and obligatory exercises are included in the course.
Compulsory assignments
- Exercises
Further on evaluation
Compulsory assignments must be approved in order to attend the exams.
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.
If there is a re-sit examination of the written exam, the examination form may be changed from written to oral exam. Re-sit of any other partial assessments must be done in a semester when the course is taught.
Recommended previous knowledge
Based on the course TBA4236 Theoretical Geomatics.
