Satellites used for telecommunication relay are kept in a geostationary orbit. A satellite is said to be in such an orbit when:
1. The orbit is geosynchronous.
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.

• Correct Answer: A
• Geostationary orbit requires geosynchronous period (~24h), circular orbit (eccentricity zero), and equatorial plane (inclination zero).
• Statement 4 is incorrect: geostationary altitude is ~35,786 km, not 22,236 km (which is in miles).
