What Is Satellite Station Keeping

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.

What is satellite station keeping.

In general terms a satellite is a smaller object that revolves around a larger object in space. Station keeping in low earth orbit. 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. 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.

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. Satellite communication introduction. 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. We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel.

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. 11 24 2015 at 1 27 pm reply. For example moon is a natural satellite of earth. 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.

Once the satellite accumulation drum was full or the 1 year limit reached then business has 3 days to move the waste to the hazardous waste accumulation area and dispose of this waste within the time frame that the. Orbital station keeping for earth observation spacecraft. In other words it is nothing but sending receiving and processing of. Geosatellite nssk gmat inclination maneuver orbit маневр орбита.

In other words the control routine necessary to keep the satellite in positionis known as station keeping. 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. 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.
