Some artificial satellites are used for telecommunication, which enable us to make telephone calls to any part of the world, to see 【C4】______ television transmissions and to communicate via the Internet. Other artificial satellites are used for navigation, so that people on Earth can know at any moment the position of an object, within a few meters.
