Prograde orbit having a period equal to that of the Earth's rotation (need not imply geostationary).
An orbit where the period of the satellite is equal to the period of the rotation of the Earth. This is usually used synonymously with geostationary, although the latter has the additional qualities of being circular and in the equatorial plane.
An orbit of approximately 22,300 miles at which the movement of the satellite around the earth exactly matches the rotation of the earth. The effect is that the satellite appears to stay in a relatively stationary position above the earth. Communication and early warning satellites often use this type of orbit. [Return
Edit / Also known as geostationary. Describes the orbit of a satellite that remains stationary over a single geographic point on earth (i.e. synchronized to a geographic position on earth). This is accomplished by orbiting the satellite at a distance of 22,300 miles (35,900 km) above the equator. At this distance, an object orbits the earth at the same speed the earth rotates (approximately once every twenty-four hours) and so the object appears to remain stationary above the point. Geosynchronous satellites are useful for many applications but not for two-way conversations. The reason for this is that it takes radio waves almost a quarter of a second to make the round trip (44,600 miles at 186,000 miles/second). This added to other delays in the normal transmission of digitized audio and video produces unacceptable latency during conversations. LEO (Low Earth Orbiting) satellites orbit the earth at only a few hundred miles and so do not suffer from the latency problem. See Also: Jitter LEO Latency
An orbit whose period is equal to the rotational rate of the earth. Geosynchronous satellites' groundtracks are figure eight shaped.
The position in space (at an altitude of 22,237 miles) where the speed of the satellite matches the speed of Earth's rotation.
of or having an orbit with a fixed period of 24 hours (although the position in the orbit may not be fixed with respect to the earth)
Term applied to any equatorial satellite with an orbital velocity equal to the rotational velocity of the Earth. The net effect is that the satellite is virtually motionless with respect to an observer on the ground.
A direct, circular, low inclination orbit about the Earth having a period of 23 hours 56 minutes 4 seconds.
An orbit in which a satellite's rate of revolution matches the Earth's rate of rotation. This allows the satellite to stay over the same site on the Earth's surface at all times.
Refers to the orbit in which the speed of a satellite's orbit is synchronized with the speed of the earth's rotation so that they are always positioned above the same spot on the earth. For this to occur, the satellite must be in orbit 22,300 miles over the equator, Most communications satellites are in geosynchronous orbit.
Geosynchronous refers to a special type of orbit around the Earth, where an object orbits the Earth in the same direction and at the same speed as the Earth's own rotation. This results in the orbiting object remaining in a fixed position above a geographic point on the surface of the Earth. Telecommunications satellites are often put into geosynchronous orbit so that they may be accessible via radio waves from one area of Earth at all times.
An object orbiting the earth at the earth's rotational speed and with the same direction of rotation. The object will appear at the same position in the sky at a particular time each day, but will not appear stationary if not orbiting in the equatorial plane.
The Clarke circular orbit above the equator. For a planet the size and mass of the earth, this point is 22,237 miles above the surface.
Refers to an orbit with a period equal to one day. A satellite in geosynchronous orbit above Earth's equator will stay over the same point on Earth at all times. Communications satellites are often put in geosynchronous orbits so that satellite dishes on earth can remain pointed at the same point in the sky at all times.
A satellite with an orbital period equal to the earth's rotation period, and approximately 22,237 miles, or 35,579 Km above the earth's surface. Horizontal -- This is the B-Pol transmit polarization on a Ku-band antenna.
