Communications

Communications satellites allow radio, television, and telephone transmissions to be sent live anywhere in the world. Before satellites, transmissions were difficult or impossible at long distances. The signals, which travel in straight lines, could not bend around the round Earth to reach a destination far away. Because satellites are in orbit, the signals can be sent instantaneously into space and then redirected to another satellite or directly to their destination.
navigation
Police cars, Ambulances, Fire Engines so the users know where to go. If the services get an emergency call they will get the location from the call centre operator, they will then proceed to that location, if they don't know where it is they'll tap what the call centre operator told them into the SatNav in thier vehicle and away they go. The army also use SatNav to locate certain points on a map where they would like to go or to drop airstrikes or missiles onto the location.
Collecting weather data
The history of weather forecasting and early satellite programmes is told using archive film, highlighting the difficulties associated with a lack of weather data. Two hundred dedicated weather satellites have been launched since the 1960s. Together, these satellites enable us to monitor every weather system around the world and to see the weather as it approaches.
Research
Satellites play a major role in research. they are collect information the space, regions, climate and count population of animals, birds and even human beings. they research the available mineral resources and destinate an accurate place in which the mineral are available. most human researches are nothing if satellites are not used.
