SOLAR SYSTEM

Detailed explanation-1: -A geostationary orbit can be achieved only at an altitude very close to 35, 786 kilometres (22, 236 miles) and directly above the equator. This equates to an orbital speed of 3.07 kilometres per second (1.91 miles per second) and an orbital period of 1, 436 minutes, one sidereal day.

Detailed explanation-2: -Three conditions are required for an orbit to be geostationary: The satellite must travel eastward at the same rotational speed as the earth. The orbit must be circular. The inclination of the orbit must be zero.

Detailed explanation-3: -Geostationary orbits of 36, 000km from the Earth’s equator are best known for the many satellites used for various forms of telecommunication, including television. Signals from these satellites can be sent all the way round the world.

Detailed explanation-4: -A majority of U.S. long distance companies utilize geostationary satellites to provide back-up capacity for telephony service. Examples of GEO satellite systems include INTELSAT, Inmarsat, and PanAMSat. The geostationary orbit typically provides coverage from 20 degrees north latitude to 20 degrees south latitude.

Detailed explanation-5: -The orbit of a geostationary satellite is known as the parking orbit. It takes 24 hours to complete one revolution of the earth by satellite, that is the same time as the earth takes to rotate once on its axis.
