WebRegarding proximity, we'll need a good database first. For example, Eric Johnston publishes on a SatSig.net page a list of satellites in Geostationary Orbit (GEO) that was last updated on 21 Feb 2014, so fairly recent. I couldn't find more complete list, but this individual has been upkeeping the list for a fairly long time (some older pages where he collated these … WebIn order to keep geostationary satellites within the prescribed boundaries to satisfy mission requirements, orbital station keeping manoeuvres are performed periodically to …
WebAccording to one embodiment of the invention, a stationkeeping method for a geostationary satellite includes determining a gravitational force of the sun on the … In astrodynamics, orbital station-keeping is keeping a spacecraft at a fixed distance from another spacecraft or celestial body. It requires a series of orbital maneuvers made with thruster burns to keep the active craft in the same orbit as its target. For many low Earth orbit satellites, the effects of non-Keplerian forces, i.e. the deviations of the gravitational force of the Earth from that of a homogeneous sphere, gravitational forces from Sun/Moon, solar radiation pressure and air drag, …
