Theoretical Geodesy 4 introduces students to the field of space geodesy, i.e. using satellite observations of the Earth to define and maintain global coordinate systems, the Earth orientation parameters, models of the Earth's gravity field and ocean topography. The outputs of space geodesy form the basis from which one of the most widely used measurement techniques in geodesy – GNSS – is based.
