Course responsible: Vegard Ophaug
ECTS credits: 10
Faculty: Faculty of Science and Technology
Teaching language: EN, NO
(NO=norsk, EN=Engelsk)
Teaching exam periods:
This course starts in Spring parallel. This course has teaching/evaluation in Spring parallel.
Course frequency: Annually
First time: 2020H
Preferential right:
M-GEOM
Course contents:
The course covers mathematical models and methods used for describing Earth's gravity field: gravitation, rotation and potential, terrestrial and satellite gravimetry, geoid computation and height systems, including elements from parameter estimation and statistics.
Learning outcome:

The students will learn the theoretical basis for computation methods and measurement techniques in physical geodesy, and apply this to problems in geoid computation and height systems.

By the end of the course, the students will be able to describe a physical reference system including its gravity field, perform measurements with relative and absolute gravimeters, implement numerical computation methods for the determination of Earth's gravity field and the geoid, and apply these to gravity data from terrestrial and satellite-based sensors.

Learning activities:
Lectures, colloquium work, student presentations, exercises.
Teaching support:
Teaching support will be given primarily in connection with that part of the structured teaching that is set aside for exercise guidance. It will also be possible to communicate directly with the subject teacher by appointment during office hours.
