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.
Satellite station-keeping. Geostationary satellites are in orbit above the equator and go around the earth in the same direction as the earth rotates and at the same angular speed. They appear virtually stationary in the sky, so your satellite dish can see the satellite all of the time.
Stationkeeping is the ongoing process of maintaining a satellite’s position within its intended orbit. It involves using propulsion systems and control mechanisms to counteract orbital perturbations caused by various factors, such as gravitational forces from celestial bodies, atmospheric drag, and solar radiation pressure.
Satellites in the 6/4-GHz band must be kept within 0.1° of the desig- nated longitude, and in the 14/12-GHz band, within 0.05°. In addition to having its attitude controlled, it is important that a geo- stationary satellite be kept in its correct orbital slot.
What is the station keeping in satellite communication? The orbit control process required to maintain a stationary orbit is called station-keeping. Station-keeping is necessary to offset the effect of perturbations, principally due to the Earth’s triaxiality and lunar and solar attractions, which tend to precess the orbit normal and alter ...
In order to build one constellation system, the lifecycle satellite constellation design comprises configuration design, deployment strategy, reconfiguration strategy, reinforcement strategy, and...
Satellite station-keeping refers to the series of maneuvers and control strategies implemented to maintain a satellite within its assigned orbital slot. This process is crucial for ensuring the satellite’s optimal functionality, as well as its adherence to regulatory and contractual obligations.
The NOM Geostationary Operational Environmental Satellites (GOES) fire thrusters to remain within a 1" longitude-latitude box and to dump accumulated angular momentum.
The orbit control process required to maintain a stationary orbit is called station-keeping. Station-keeping is necessary to offset the effect of perturbations, principally due to the Earth's triaxiality and lunar and solar attractions, which tend to precess the orbit normal and alter the orbital energy.
the improved method for satellite station keeping of the present invention is not limited to earth orbit satellites, but may be used for orbit or maneuvering control of other types of...
