Learning outcomes of the course unit

Student gets overview of transformation, acquaintances with basic principles and methods of measurement and orientation of geodetic networks, gyroskopic and magnetic measurement and basic of space geodesy.

Prerequisites

Fundamental knowledge of mathematics, geometry and physics. Knowlendge of basic geodetic measurement and computation.

Co-requisites

The student should have basic knowledge of physics and mathematics, knowledge from studies at secondary geodetic technical schools is welcome.

Planned learning activities and teaching methods

In addition to the lectures themselves and subsequent exercises, the lectures will also regularly include news from the subject, news and development perspectives. The same in the exercises with an emphasis on practical applications.

Assesment methods and criteria linked to learning outcomes

Verification of knowledge and skills takes place in exercises. Students are motivated to continuous study even during the lessons. The teacher repeatedly emphasizes essential profile information. The exam is carried out in the form of a test as well as in writing. Evaluation is carried out according to valid principles with a set scale of evaluation.
