Introduction to geostationary orbit satellite:
The satellite which appears stationary to an observer on earth’s surface is called geostationary satellite. In circular orbit, the satellite placed in between the equator of earth and around earth. The speed and direction are similar as earth.In the equator, the altitude of satellite is 36,000km.The directional antenna and dish is used for direct the satellite.
Geostationary satellite in orbit
Explanation for geostationary orbit satellite:
The ‘INSET’ group of satellites launched by india are geostationary satellites these are being widely used for telecommunication. For such a satellite,
Such an orbit is called geostationary or parking orbit or clarke geosynchronous orbit after the famous scientist Arthur C. Clarke. A geostationary satellite is very useful for transmission of T.V. programmes, radio and telephone talks, therefore, it is also called synchronous communication satellite abbreviated as SYNCOMS.
Orbital speed of syncoms: v0 =`(2Pir)/(T)` = 2 x 3.14 x (4.22 x 107 m) / 24 x 60 60s
= 2 x 3014 x 4.22 x 107 m / 8.64 x 105 s = 3.07 x 102 m/s.

Explanation for geostationary orbit satellite:
The ‘INSET’ group of satellites launched by india are geostationary satellites these are being widely used for telecommunication. For such a satellite,
- The orbit of satellite should be circular and coplanar with the equatorial plane of earth.
- The angular velocity of satellite should have same magnitude and direction as that of earth that is its angular velocity should be from west to east and period of revolution 24 hours.
Such an orbit is called geostationary or parking orbit or clarke geosynchronous orbit after the famous scientist Arthur C. Clarke.

Advantages and disadvantages of geostaionary orbit satellite:
- This is used in meterological study.
- The earth based sources produce the signal interventions.This is reduced by directional dish antenna.
- The television broadcasting, weather forecasting and worldwide communication are use this orbit satellite.
