Also, it is very easy to transmit a carrier radio signal to a geostationary satellite and thus interfere with the legitimate uses of the satellite's transponder. A satellite of the latter kind is known as a geostationary satellite and it plays an instrumental role in global communications and weather forecasting. When launching geostationary satellites, it is important that the satellites can be launched towards the east, where the launch impulse is aided by the spin of the Earth. GPS satellites are potential targets for jamming, but satellite phone and television signals have also been subjected to jamming. Satellite communication is used in telephone, radio, television, internet and military applications. The smallest inclination that a satellite can be launched into is that of the launch site's latitude, so launching the satellite from close to the equator limits the amount of inclination change needed later. 4.

Because geostationary satellites circle the earth at the equator, they are not able to provide coverage at the Northernmost and Southernmost latitudes. Radius of orbit = 42400 km. 4. The orbits of the satellites are known as the geosynchronous orbit and geostationary orbit. GEOSTATIONARY SATELLITES A geosynchronous satellite is a satellite whose orbital track on the Earth repeats regularly over points on the Earth over time. Geostationary satellite are used for telecommunication and polar satellite for remote sensing. Advantages: Weather images can be displayed. 1. ii. 5. 2. identify the uses of satellite in their communities. These are low altitude satellites.This means they orbit around earth at lower heights. They orbit around the earth in North-South direction.Whereas earth is moving from East to West. these satellites are stationery with reference to the earth they can observer a specific portion of the earth continuously.
