Question

The altitude of geostationary
orbits
in
which
communication satellites are
launched above the surface
of the Earth is:
(a) 850 km (b) 1000 km
(c) 6400 km (d) 42,300 km​

Answer 1

The altitude of geostationary orbits in which communication satellites are launched above the surface of the Earth is:

(d) 42,300 km

• Geostationary orbit is also known as the special type of geosynchronous orbit.It is a circular geosynchronous orbit in Earth's equatorial plane.

• It has a constant altitude of 35,786 km.

• Geostationary orbit is close to the communication satellite , so that the satellite antennas that communicate with them donot have to move as they are near them. As, they don't move so they can be pointed permanently in the sky at the fixed location where the satellite appears.
