A satellite is in geostationary orbit when it remains over the same spot on the Earth (somewhere along the equator). The orbital period is 24 hours (equal to the earth's rotational period). A geostationary orbit is geosynchronous, circular and has zero inclination. There is only one geostationary orbit, a belt encircling the earth's equator at an altitude of about 22,236 miles (35,786 km). It is impossible to have a satellite in geostationary orbit over a point that is not along the equator.
An orbit which circles the Earth above the equator from east to west at an attitude of 36Â 000Â km (GEO)
The circular orbit at 35.780 km above the equator. Satellites slotted on this orbit always appear at the same position in the sky. In degrees towards East (E or positive) or West (W or negative) from the Greenwich meridian.
An orbit lying above the Equator in which an artifical satellite moves at the same speed as the Earth rotates. As such it maintains position above the Earth's surface. Such satellites have an altitude of 35,800 km. Satellites in this type of orbit have a continuous view of the full disc of the Earth, although the curvature of the Earth makes it diffucult to gather information for latitudes higher than about 45-50 .
describes the orbit of a satellite whose position relative to the earth's surface is constant so it appears to hover over one spot on the earth's equator.
Satellites orbit the Earth approximately 22,300 miles above the Equator and travel at the same speed and direction as the Earth's rotation, thus appearing to be stationary.
An orbit in which a satellite is always in the same position with respect to the rotating Earth. The satellite travels around the Earth in the same direction, at an altitude of approximately 22,000 miles (35,800 kilometers).
a geosynchronous orbit that is fixed with respect to a position on the Earth
a circular orbit directly above the Earth's equator, and it orbits in the same direction and speed as the Earth's rotation
a circular orbit in the equatorial plane, any point on which revolves about the Earth in the same direction and with the same period as the Earth's rotation
an orbit in which a satellite is always in the same position (appears stationary) with respect to the rotating Earth
an orbit with zero inclination (i
a special case of a geosynchronous orbit
a special kind of geosynchronous orbit
The normal placement for communication satellites 22,300 miles above the Earth's equator. In this orbit, satellite appear to stay in a fixed position above the Earth.
a circular orbit around the Earth's equator, at a distance of 6.6 Earth radii. At this distance the orbital period is 24 hours, keeping the satellite "anchored" above the same spot on Earth. This feature makes the synchronous orbit useful for communication satellites: a satellite transmitting TV programs to the US, for instance, will always be in touch with the US if "anchored" above it, and receiving antennas on the ground only need to point to one fixed spot in the sky.
The orbit of a satellite which is both geosynchronous and in the equatorial plane. The satellite will appear to remain in a fixed position in relation to the observer.
On orbit over the equator that takes 24 hours to complete so that the satellite stays in the same part of sky relative to the ground. The Earth and beyond
The orbit of a communications satellite that allows it to move at the precise speed at which the Earth is rotating, thus remaining at the same spot in the sky relative to the Earth. The orbit is 35,900 km (22,300 mi) above the Earth and directly over the equator.
Special geosynchronous orbit which is circular and lying over the equator such that the satellite seems to remain stationary in the sky as seen form a location on the surface of the Earth.
An orbit in which a satellite revolves about the earth's equator at the same rate at which the earth rotates on its axis. From the earth, the satellite thus appears to be stationary.
The circular orbital belt at 35786 kilometers above the equator, in which satellites travel at the same speed as the earth's rotation. Also called Clarke Belt after the writer Arthur C. Clarke.
An satellite in a geostationary orbit around the Earth is always above exactly the same point on the surface. This type of orbit has a period of one day. Satellites and Orbits
A method of keeping a satellite parked over the same spot on earth all the time. The satellite is put into an orbit so it travels around the earth at the same speed as the earth is turning on its axis. From earth, the satellite thus appears to be parked. Most communications satellites are in an orbit 22,300 miles (35,800 Km) over the equator. The main uses of GEO satellites are: signal relays for broadcast, cable and direct TV; meteorology; intelligence operations; mobile maritime telephony.
An altitude above the earth of 22,300 miles. Satellites in this orbit are synchronised with the rotation of the earth and so appear stationary relative to the earth's surface. This contracts with satellites in low earth orbit.
is what keeps communica-tions satellites stationary over a specific place on the Earth. If they moved across the sky in another type of orbit, the trans-mitting and receiving antennas would have to move to follow them.
is a satellite orbit which is fixed at a speed that will keep it exactly above a certain ground position
An orbit whose period equals the rotation period of the Earth. Artificial satellites are usually placed in geosynchronous at 35,800km altitude.
A geosynchronous orbit with an inclination of zero degrees. A spacecraft in such an orbit appears to remain fixed above a particular point on the equator.
Any orbit at an altitude of 23,000 miles above the equator traveling at a velocity and in a direction that keeps pace with the Earth's rotation, making it appear to be stationery in the sky (see Geosynchronous).
An orbit at 35,786 km directly over the Earth's equator in which the orbital inclination and eccentricity are both near zero such that the satellite appears to hover over a specific portion of the Earth's equator. See also Clarke Belt.
circular orbits that are orientated in the plane of the earth’s equator. The satellite appears stationary.
the most desirable orbital position or slot for a communications satellite. When a satellite is placed in such an orbit, which is at an altitude of 22,300 miles above the earth's equator, the satellite's motion is synchronized with the earth's rotation. The satellite appears, at least to a ground observer, to be stationary in the sky.
An orbit whose rotation period equals that of the Earth. The altitude of a geostationary orbit is approximately 35,800 km.
The orbit of a geosynchronous satellite whose orbit lies in the plane of the earth's equator.
An earth orbit located directly above the equator, approximately 22,300 miles above the surface. Satellites in this orbit rotate at the same relative speed as the earth itself. This allows earth antennas to remain fixed.
An equatorial orbit that takes 24 hours to complete. The satellite therefore takes as long to make one full rotation of the earth as the earth itself and this means that the satellite appears to remain stationary above the same point of the earth's surface.
An orbit in which a satellite appears to remain in the same spot in the sky all the time. When a satellite is in geostationary orbit, it travels at exactly the same speed as the Earth is rotating below it. A satellite in geostationary orbit is very high up, at 35 850 km above the Earth. Geostationary satellites are always located directly above the equator. The area with which a satellite in geostationary orbit can communicate is called its footprint.
A geostationary orbit (GEO) is an geosynchronous orbit directly above the Earth's equator (0º latitude). From the ground, a geostationary object appears motionless in the sky and is therefore the orbit of most interest to operators of artificial satellites (including communication and television satellites). Due to the constant 0° latitude, satellite locations may differ by longitude only.
