Geostationary Satellite Orbit Height

A special case of geosynchronous orbit is the geostationary orbit which is a circular geosynchronous orbit in earth s equatorial plane.

Geostationary satellite orbit height. Specifically geosynchronous earth orbit geo may be a synonym for geosynchronous equatorial orbit or geostationary earth orbit. A low earth orbit leo typically is a circular orbit about 160 to 2 000 kilometres 99 to 1 243 mi above the earth s surface and correspondingly a period time to revolve around the earth of about 90 minutes. A satellite in a geostationary orbit appears stationary always at the same point in the sky to ground observers. Originally spacex intended to launch 4 425 satellites to non geostationary orbits ngso ranging from 1100 and 1300 km 680 and 800 mi which would transmit in the ku and ka radio bands.

A satellite in a geostationary orbit remains in the same position in. We can calculate the height h above the earth s surface by subtracting the radius of the earth from the radius of the orbit. Popularly or loosely the term geosynchronous may be used to mean geostationary. At any inclination a geosynchronous orbit synchronizes with the rotation of the earth.

Because of their low altitude these satellites are only visible from within a radius of roughly 1 000 kilometres 620 mi from the sub satellite point. H 4 22 10 7 6 37 10 6 3 583 10 7 m. A geostationary orbit is valuable for the constant view it provides but satellites in a geostationary orbit are parked over the equator so they don t work well for far northern or southern locations which are always on the edge of view for a geostationary satellite. This distance puts it in the high earth orbit category.

From the center of the earth this is approximately 42 164 kilometers. At that height the eastward motion of the satellite coincides exactly with earth s rotation so that the satellite remains in one position above the equator. 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. A circular geosynchronous orbit has a constant altitude of 35 786 km 22 236 mi and all geosynchronous orbits share that semi major axis.

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. About 35 786 kilometers above the earth s surface satellites are in geostationary orbit. The geostationary satellite is made to orbit earth along its equatorial plane at an altitude of about 36 000 kilometres.

That orbital speed and distance permit the satellite to make one revolution in 24 hours.
