Orbital Period Of Communication Satellites

There are about 2 000 communications satellites.

Orbital period of communication satellites. Length of semi major axis a not only determines the size of satellite s orbit but also the time period of revolution. Company collided with a non functioning russian satellite. Where v is the orbital velocity of. Satellite communication orbital mechanics we know that the path of satellite revolving around the earth is known as orbit.

The most common altitude is approximately 20 200 kilometres 12 552 mi which yields an orbital period of 12 hours as used for example by the global positioning system gps. A geosynchronous orbit sometimes abbreviated gso is an orbit about the earth in which a satellite has an orbital period that matches the rotation of the earth on its axis one sidereal day of approximately 23 hours 56 minutes and 4 seconds. The third reason to move a satellite is to avoid space junk orbital debris that may be in its path. On 4 october 1957 the soviet union launched the world s first artificial satellite sputnik 1 since then about 8 900 satellites from more than 40 countries have been launched.

With satellites the object is not to escape earth s gravity but to balance it. The period of the earth as it travels around the sun is one year. Both satellites broke apart creating a field of debris that contained at least 2 500 pieces. A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder.

This is approximately 17 000 mph 27 359 kph at an altitude of 150 miles 242. The period of a satellite is the time it takes it to make one full orbit around an object. In the context of spaceflight a satellite is an object that has been intentionally placed into orbit these objects are called artificial satellites to distinguish them from natural satellites such as earth s moon. Located at 22 236 miles 35 786 kilometers above earth s equator this position is a valuable spot.

It creates a communication channel between a source transmitter and a receiver at different locations on earth communications satellites are used for television telephone radio internet and military applications. The orbit is home to a number of artificial satellites the most common uses include navigation communication and geodetic space environment science. Orbital velocity is the velocity needed to achieve balance between gravity s pull on the satellite and the inertia of the satellite s motion the satellite s tendency to keep going. You can calculate the speed of a satellite around an object using the equation.

A geosynchronous orbit is a high earth orbit that allows satellites to match earth s rotation. If you know the satellite s speed and the radius at which it orbits you can figure out its 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.
