What Is Satellite Station Keeping

Orbital station keeping for earth observation spacecraft.

What is satellite station keeping.

Satellite communication introduction. Geosatellite nssk gmat inclination maneuver orbit маневр орбита. 11 24 2015 at 1 27 pm reply. The main source of perturbation for a satellite in gso is the combined gravitational attractions of the sun and moon which causes the orbital inclination to increase by nearly one degree per year.

The purpose of geo station keeping is to keep the geo satellite longitude and latitude point inside the rectangular deadband box 4. Let λ d b be the e w maximum allowed. I was under the impression that you could accumulate hazardous waste up to 1 year at a satellite accumulation area and up to 55 gallons. In other words the control routine necessary to keep the satellite in positionis known as station keeping.

An east west station keeping ewsk maneuver controls the satellite longitude drift rate and eccentricity to maintain the satellite in the pre defined longitude box. We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel. In other words it is nothing but sending receiving and processing of. For a spacecraft in a very low orbit the atmospheric drag is sufficiently strong to cause a re entry before the intended end of mission if orbit raising manoeuvres are not executed from time to time.

For example moon is a natural satellite of earth. Station keeping is minor maneuvers that a satellite in geostationary orbit gso or low earth orbit leo must make over its mission life to compensate for orbital perturbations. It may be used like visualization for educational classes. Station keeping in low earth orbit.

For earth observation spacecraft an earth observation satellite or earth remote sensing satellite is a satellite specifically designed for earth observation from orbit similar to spy satellites but intended for non military uses such as environmental monitoring meteorology map. An example of this is the international space station iss which has an operational altitude above earth s surface of between 330 and 410 km. In astrodynamics the orbital maneuvers made by thruster burns that are needed to keep a spacecraft in a particular assigned orbit are called orbital station keeping. Simultaneous control of the eccentricity and longitude of geostationary satellites have been studied by biasing mean eccentricity vector relative to the sun kamel and wagner.
