Communication, weather prediction, global monitoring, GPS, espionage, space exploration etc.
GPS satellites do not 'find' anything, that is not their purpose.
The purpose for having communication satellites in space, is by providing telecommunication throughout the world. Communication satellites are mostly used for mobile phone signals, weather tracking, and broadcasting television programs.
No. The earth has one natural satellite ... the moon ... and any number of other satellites whose primary purpose is not scientific (e.g. communication satellites).
The same way we do ANYTHING these days; by computers sending radio commands.
The purpose of communications satellites are to provide telecommunication for companies around the world. In addition, communication satellites are also used for mobile applications such as communication to ships, vehicles, and planes.
The purpose of sending Christmas Cards to anyone (including acquaintances) is to wish them well during the Holiday season.
There are billions and billions of satellites they are all diffrent shapes and sizes here is a list of types.NavigationCommunicationExplorationWeatherAstronomyMilitaryReserch
hi
Engineers keep the masses of satellites as small as possible to reduce the overall cost of sending them into space, as heavier satellites require more fuel and resources for launches. Additionally, smaller satellites are more maneuverable and flexible in their deployment options in space.
No, satellites should not fly on people because they are designed to orbit the Earth or travel through space autonomously. Placing satellites on people would be impractical, dangerous, and inefficient for their intended purpose.
The Hot Bird satellites are operated by Eutelsat. They are used for broadcasting digital TV and radio signals to continental Europe and northern Africa.
The network of 36 satellites orbiting Earth for the purpose does.
