Calculate The Orbital Height Of A Geostationary Satellite
B calculate the height at which the satellite orbits above the surface of the earth.
Calculate the orbital height of a geostationary satellite. The height of the geostationary orbit is 35786 kilometers above earth in geostationary orbit the satellite moves with an orbital speed of 11068 km per hours. From the relationship f centripetal f centrifugal we note that the mass of the satellite m s appears on both sides geostationary orbit is independent of the mass of the satellite. An object s orbital altitude can be computed from its orbital period and the mass of the body it orbits using the following formula. A a geostationary orbit is when the satellite remains vertically above the same point on the equator at all all times and consequently has an orbital period of 24 hours.
H is the altitude height of the object. A minimum of three satellites are needed to cover the entire earth super synchronous orbit is a disposal storage orbit above gso. 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. The satellite must have a period.

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.
From earth they would seem drifting in westerly direction. 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. R orbital radius earth s equatorial radius height of the satellite above the earth surface r 6 378 km 35 780 km r 42 158 km r 4 2158 x 107 m speed. Because the radius and period are related you can use physics to calculate one if you know the other.
Image satellites in geostationary orbit by lookang many thanks to author of original simulation francisco esquembre author of easy java simulation francisco esquembre. R g m2 t 4π we know that m2 is the mass of the earth at 5 98 10 24 kg t is the time period and g the universal gravitation constant at 6 67 x10 11 kg 2. G is the gravitational constant. To calculate the radius of a geostationary orbit the centripetal force must equal the gravitational force on the satellite or mass.
We can calculate the height h above the earth s surface by subtracting the radius of the earth from the radius of the orbit. Mission control wishes to place a satellite in circular orbit above the earth. The period of a satellite is the time it takes.
