Short description: The course develops the skills and knowledge of existing and planned satellite missions in geodesy, geophysics and astronomy with the specification of equipment and instruments carried on the satellites. The course teaches the principles of determining the trajectory of celestial bodies in the field of gravity of n-bodies and sources of orbit perturbations for artificial satellites.

Learning outcomes: Knowledge 1.The student has knowledge of existing and planned satellite missions in geodesy, geophysics and astronomy with the specification of instruments located on the satellites. 2.The student has advanced knowledge on the acquisition and analysis of parameters describing the figure of the Earth using geodetic techniques. Skills 1. Student can specify the precision characteristics of instruments for a particular scientific problem. 2. The student is able to determine the trajectory of a celestial body in the gravity field of n-bodies and knows the source of orbit perturbations of artificial satellites. Social competences The course allows acquiring basic knowledge of the design and planning of satellite missions for testing geodetic and geophysical data and detailed knowledge on the analysis of geodetic observations. A preparation of the satellite mission project requires the cooperation of the group.
