Answer 1

A geosynchronous orbit is a high Earth orbit that allows satellites to match Earth's rotation. Located at 22,236 miles (35,786 kilometers) above Earth's equator, this position is a valuable spot for monitoring weather, communications and surveillance.

Answer 2

1) Depending on the height of satellites above the Earths surface, how are satellite

=> There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. Many weather and some communications satellites tend to have a high Earth orbit, farthest away from the surface.

2) What is the use of geosynchronous satellite.

=> A geosynchronous orbit is a high Earth orbit that allows satellites to match Earth's rotation. Located at 22,236 miles (35,786 kilometers) above Earth's equator, this position is a valuable spot for monitoring weather, communications and surveillance.

3) In how many hours do satellites complete one revolution in polar orbits.

=> Orbital period : Time taken by a satellite to complete one revolution in its orbit around the earth is called orbital period. It varies from around 100 minutes for a hear-polar earth observing satellite to 24 hours for a glo stationary satellite.

4) What is height of low Earth orbits

=> A low Earth orbit (LEO) is, as the name suggests, an orbit that is relatively close to Earth's surface. It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth – which is low compared to other orbits, but still very far above Earth's surface.

5) Which satellites are used in applications like meteorology and for carrying signals

=> Uses of Communication Satellites:

The communication satellites are used for sending microwave and TV signals from one place to another. The communication satellite is used for telephony. The communication satellites are used for weather forecasting.
