This chapter presents the models to describe planetary geometry, with focus on the Earth's ellipsoid and geoid. It also includes a brief introduction to position representation methods for objects on and above the planetary surface. An introduction to the most relevant coordinate reference systems is presented, together with the methods to transform the coordinates from one reference system to another one. The most useful time systems used in Guidance, Navigation and Control (GNC) applications are listed as well.

Abstract

This chapter presents the models to describe planetary geometry, with focus on the Earth's ellipsoid and geoid. It also includes a brief introduction to position representation methods for objects on and above the planetary surface. An introduction to the most relevant coordinate reference systems is presented, together with the methods to transform the coordinates from one reference system to another one. The most useful time systems used in Guidance, Navigation and Control (GNC) applications are listed as well.
