Learning outcomes of the course unit

Student penetrates deeper into the issue of the gravity field of the Earth, global and regional geodetic networks. Is discussed in detail the issue of vertical deviations, geoid modeling, theory of heights and quasigeoid.

Prerequisites

Computing geodetic problems on the sphere and ellipsoid

Co-requisites

Geophysics and geodynamics

Planned learning activities and teaching methods

The course is taught through lectures, practical classes and self-study assignments. Attendance at lectures is optional, but attendance at classes is compulsory.

Assesment methods and criteria linked to learning outcomes

Attendance at seminars is compulsory (2 outs can be apologized). They write the four written tests - the sum of points of all tests must be at least 50% of the total achievable points from all tests. Missed test will be replaced in the agreed date. All required programs must be completed. The exam is composed from test, numerical and oral part. 30% of the points are generated from the exercise evaluation. The total number of points is 100, for the successful completion of the exam 50% of points
