WebStation-keeping with phasing maneuvers. In a geostationary orbit that is not subject to perturbing forces, a satellite will remain directly over the equator at a set longitude λE. If we include J2 and higher order effects, the satellite will begin to move with respect to the surface of the earth. a. Suppose the longitude the satellite is located WebApr 14, 2024 · Geostationary orbit (GEO): Satellites in geostationary orbit (GEO) circle Earth above the equator from west to east following Earth’s rotation – taking 23 hours 56 minutes and 4 seconds – by travelling at exactly the same rate as Earth.

WebSep 29, 2024 · Station-keeping (SK) is indispensable in actual geostationary (GEO) satellite missions. Due to the luni-solar gravity perturbations, the inclination of a GEO satellite suffers the issues of secular drift and long-period oscillation.

A spacecraft cannot directly enter an orbit at an inclination lower than the latitude its launch site. For a launch from the Kennedy Space Center, this inclination is 28.5°. A geostationary orbit is necessarily equatorial, with an inclination of 0°, so the maneuvers must also decrease
