Uses of satellites:

(i) Satellite communication: Communication satellites are used to send radio, television and telephone signals over long distances. These satellites are fitted with devices which can receive signals from an Earth – station and transmit them in different directions.

(ii) Weather monitoring: Weather satellites are used to photograph clouds from space and measure the amount of heat reradiated from the Earth. With this information scientists can make better forecasts about weather. You might have seen the aerial picture of our country taken by the satellites. Which is shown daily in the news bulletin on the television and in the news papers.

(iii) Remote sensing: Collecting of information about an object without physical contact with the object is known as remote sensing. Data collected by the remote sensing satellities can be used in agriculture, forestry, drought assessment, estimation of crop yields, detection of potential fishing zones, mapping and surveying.

(iv) Navigation satellites: These satellites help navigators to guide their ships or planes in all kinds of weather.
