Velocity Of Geostationary Satellite Is Nearly

Mass of the earth 6xx10 24 kg and radius 6400 km.

Velocity of geostationary satellite is nearly.

Comparison of geostationary earth orbit with gps glonass galileo and compass medium earth orbit satellite navigation system orbits with the international space station hubble space telescope and iridium constellation orbits and the nominal size of the earth. The orbital velocity of this satellite is nearly 3 08 km sec. Because the satellite stays right over the same spot all the time this kind of orbit is called geostationary geostationary orbits are ideal for weather satellites and communications satellites. Since earth also rotates once in 24 hours a satellite at 22 223 miles altitude stays in a fixed position relative to a point on earth s surface.

A geostationary orbit also referred to as a geosynchronous equatorial orbit geo is a circular geosynchronous orbit 35 786 kilometres 22 236 miles above earth s equator and following the direction of earth s rotation. Thanks to physics if you know the mass and altitude of a satellite in orbit around the earth you can calculate how quickly it needs to travel to maintain that orbit. This type of satellite is used for communication purposes. The velocity which is required to keep the satellite revolves around its orbit is called orbital velocity of a satellite period of satellite height of satellite geostationary satellite height of geostationary satellite speed of satellite.

The angular velocity of any revolving body is th. An object in such an orbit has an orbital period equal to the earth s rotational period one sidereal day and so to ground observers it appears motionless in a fixed. The time period for the geostationary satellite is same as that for the earth i e 24 hours. The relative velocity of geostationary satellite with respect to earth is zero.

Orbital velocity of a satellite. The name geostationary satellite comes from the fact that it apparently appears stationary from the earth. What is the potential due to earth s gravity at the site of the satellite. The moon s orbit is around 9 times larger in radius and length than geostationary orbit.

From the relationship f centripetal f centrifugal we note that the mass of the satellite m s appears on both sides geostationary orbit is independent of the mass of the satellite. In space gravity supplies the centripetal force that causes satellites like the moon to orbit larger bodies like the earth. For geo the radial from the center of the earth to the satellite must have the same angular velocity as the earth itself namely 2π radians per sidereal day a sidereal day is the time it takes the earth to complete one rotation relative to inertial. ω angular velocity in radians per second.

If a satellite remains always above the same point on the earth s equator then it is in a circular geostationary equatorial orbit geo. The orbit of a geostationary satellite is called parking orbit.
