2. The orbit is circular.

3. The orbit lies in the plane of the earth’s equator.

4. The orbit is at an altitude of 22,236 Km.

Q. Which the correct answer using the codes given below:

  • a)
    1, 2, and 3 only.

  • b)
    1, 3 and 4 only.

Satellites used for telecommunication relay are kept in a geostationar...
A geostationary orbit (or Geostationary Earth Orbit - GEO) is a geosynchronous orbit directly above the Earth's equator (0° latitude), with a period equal to the Earth's rotational period and an orbital eccentricity of approximately zero. An object in a geostationary orbit appears motionless, at a fixed position in the sky, to ground observers. Communications satellites and weather satellites are often given geostationary orbits, so that the satellite antennas that communicate with them do not have to move to track them, but can be pointed permanently at the position in the sky where they stay. Due to the constant 0° latitude and circularity of geostationary orbits, satellites in GEO differ in location by longitude only.
A geostationary orbit can only be achieved at an altitude very close to 35,786 km (22,236 mi), and directly above the equator.

's equator.
4. The satellite's orbital period matches the rotation period of the Earth (approximately 24 hours).
5. The satellite appears to remain stationary in the sky when viewed from a fixed point on Earth.

Therefore, a satellite is said to be in a geostationary orbit when all five of these conditions are met.
