Description

This lecture covers the Earth-Centered-Earth-Fixed (ECEF) frame, focusing on satellite positions, orbital planes, and the longitude of the ascending node. It discusses the model versus reality in satellite orbits, including the impact of Earth's non-round shape and gravitational field. The lecture also delves into coarse orbit parameters, almanacs, and navigation messages, detailing the perturbation parameters and Keplerian parameters used in satellite positioning.
