what do satellite actually do?

Answer 1

Are you talking about natural ones or artificial ones?

Answer 2

I'll assume you mean artificial satellites.

We have satellite that control cell phone communications, satellite tv, monitor the weather, control GPS systems, take hourly images of the earth (think google earth), monitor for military activity in the forms of harmful radiation, take infrared maps of the atmosphere to watch weather patterns (GOES satellites), study the Sun for, among other things, solar flares and coronal mass ejections that might interfere with communications arrays (GOES and SOHO and RHESSI), satellites that look for gamma ray activity in the universe (SWIFT and INTEGRAL and RHESSI), satellites monitoring x-ray emissions from the universe (SWIFT and CHANDRA), ultraviolet telescopes (SOHO and SWIFT and TRACE), not to mention spy satellites and private communications satelllites and, of course, the International Space Station.

It's crowded up there!

Answer 3

Orbit.

They may do other things too, but it depends on the particular satellite and whether it's natural or artificial, and, if the latter, who put it up and for what purpose.

Answer 4

If you mean man-made satellites, they do lots of things. They broadcast satellite TV and Radio (eg, DirecTV and Sirius). They relay voice and data communications for telecom companies. They take pictures of weather for meteorologists, and collect other types of sensory data for government and academic researchers.

They take secret high-res pictures for government spy agencies. They take images in light and radio waves for astronomers (Hubble). And they help us navigate these days by broadcasting an encoded signal that your GPS device picks up.

Answer 5

Go round and round

Answer 6

I think it will let our cell phone call ,computers,telephones,and bacily every thing thta is electryity!!!!!
