What Is The Speed Of A Satellite In A Geosynchronous Orbit
A geostationary orbit is a circular orbit directly above the earth s equator approximately 35 786 km above ground.
What is the speed of a satellite in a geosynchronous orbit. However because this orbit can be titled over the earth like an angel with a lopsided halo the satellite can appear to move north and south in the sky throughout the day though it always stays over the same. The speed can t vary as long as the satellite has a constant orbital radius that is as long as it s going around in circles. Certain orbital altitudes have special properties like a geosynchronous orbit in which a satellite travels around the earth exactly once each day. A geosynchronous satellite is a satellite in geosynchronous orbit with an orbital period the same as the earth s rotation period such a satellite returns to the same position in the sky after each sidereal day and over the course of a day traces out a path in the sky that is typically some form of analemma a special case of geosynchronous satellite is the geostationary satellite which has a.
A 270 kg communication satellite is placed in a geostationary orbit 35 780 km above a relay earth ground level. Located at 22 236 miles 35 786 kilometers above earth s equator this position is a valuable spot. The length of each red arrow in this diagram represents the distance traveled by a satellite in an hour. When a satellite travels in a geosynchronous orbit around the earth it needs to travel at a certain orbiting radius and period to maintain this orbit.
This equation holds for any orbiting object where the attraction is the force of. What is the speed of the satellite in orbit. The period of a satellite is the time it takes. Geosynchronous is a term used to describe the orbit of a satellite that moves at the same speed that the earth rotates about its axis.
Because the radius and period are related you can use physics to calculate one if you know the other. A circular geosynchronous orbit has a constant altitude of 35 786 km 22 236 mi and all geosynchronous orbits share that semi major axis. This equation represents the speed that a satellite at a given radius must travel in order to orbit if the orbit is due to gravity. A special case of geosynchronous orbit is the geostationary orbit which is a circular geosynchronous orbit in earth s equatorial plane.
