Learning outcomes of the course unit

Introduction with spatial geodesy, particularly with satellite geodesy. Students become familiar with dynamism of satellite motion in gravitational field, with methods of terrestrial satellites tracking and results processing.

Prerequisites

Kinematics and dynamics of motion, Newton‘s motional laws, Newton‘s gravitational law, law of refraction and reflection of the light, dispersion of wave motion, methods of modulation of waves, field of dissipative forces, physical conditions in Earth‘s atmosphere.

Co-requisites

None

Planned learning activities and teaching methods
