Geostationary Satellite Orbits Around The Earth At A Height Of Nearly

A geostationary orbit also known as a geostationary earth orbit geosynchronous equatorial orbit or simply geo is a circular orbit located at an altitude of 35 786 kilometers 22 236 miles above the surface of earth with zero inclination to the equatorial plane.

Geostationary satellite orbits around the earth at a height of nearly. The solar and heliospheric observatory soho a nasa and european space agency satellite tasked to monitor the sun orbits the first lagrange point about 1 5 million kilometers away from earth. Radius 6400 km. This particular orbit is. In practice only 1 1 ratio geosynchronous and 1 2 ratios semi synchronous are common.

Difference between geostationary and geosynchronous satellite. The semi synchronous orbit is a near circular orbit low eccentricity 26 560 kilometers from the center of the earth about 20 200 kilometers above the surface. A satellite at this height takes 12 hours to complete an orbit. A satellite in a geostationary orbit appears stationary always at the same point in the sky to ground observers.

The second lagrange point is about the same distance from the earth but. This means the track of the satellite as seen from the central body will repeat exactly after a fixed number of orbits. Specifically geosynchronous earth orbit geo may be a synonym for geosynchronous equatorial orbit or geostationary earth orbit. The first lagrange point is located between the earth and the sun giving satellites at this point a constant view of the sun.

Mass of the earth 6xx10 24 kg and radius 6400 km. Its height from the surface of earth must be. The semi synchronous orbit and the molniya orbit. Take the potential energy at infinity to be 0 mass of the earth equal to 6 0 10 kg.

A spacecraft in this orbit appears to an observer on earth to be stationary in the sky. An orbit whose period is a rational multiple of the average rotational period of the body being orbited and in the same direction of rotation as that body. A geostationary satellite orbits the earth at a height of nearly 36000 km from the surface of the earth. Popularly or loosely the term geosynchronous may be used to mean geostationary.

For a geostationary satellite orbiting around the earth identify the necessary condition. What is the potential due to earth s gravity at the site of the satellite. Geostationary orbit a circular orbit 35 785 km 22 236 miles above earth s equator in which a satellite s orbital period is equal to earth s rotation period of 23 hours and 56 minutes. What is the potential due to earth s gravity at the site of the satellite.
