what kind of satellites beam television progams to us on Earth?

The most common satellites use a C-Band frequency which "Beams" down the programs that we watch. Star Choice, Bell Express Vu, Directv, etc all use this type of frequency for that purpose. Those same satellites all use Ka-band and Ku-band for other purposes as in Satellite Internet and so on.\nAs for the names of each one, thats a little tougher, there are over 180 satellites in the sky for commercial use.\nThis site has a list of those satellites in order by what area of earth they are "beaming" to. http://www.lyngsat.com

To operate one live, you would actually have to initiate internet-based control over an orbiting satellite with imagery capabilities.  You realize that it would have to reconfigure its current orbit and literally reposition in space to get to the place you want to spy on.  That would cost in the hundreds of thousands to operate.\nI suggest setting up internet real time cameras that are set up to a video server to relay images to your computer screen.  That way you can access a particular location but only where you have cameras set up or have access codes.

Visit:\n\nhttp://www.wunderground.com\n\nThey are the best forcasters, for all places on the globe.They have NADSTROM and other satellites working for them.

you can use a FTA (free to air) system, that allows you to get international channels free of charge.\n\nThe cost ranges from 100 to over 500 USD, depending on the system, brand and features. This price does not include the satellite antena.\n\npopular brands are pansat, fortec, coolsat, dreambox. You can search for them on ebay and on lyngsat to determine what satellite has the programming you want.

Satellites are outside of our atmosphere, in about 120 miles high.

There are two types of satellites: polar and geostationary. Polar satellites circle the earth, covering the north pole and the south pole on every circle, at an altitude of about 850 km. A geostationary satellite "moves with the earth" and is always situated over the same place over the equator, at an altitude of about 36000 km.

Yes, you can- but it takes patience and a clear sky or planning.  A very interesting form of sattelite watching are "Flares" from the Iridium satellite fleet.  These satellites have mirrors which occasionally reflect the sun's light to earth. \nhttp://antwrp.gsfc.nasa.gov/apod/ap980402.html\nTo find out when are where to catch one of these flares, go to this site:\nhttp://www.heavens-above.com/\n\nFor a more traditional satellite viewing experience, try starting out looking for the international space station.  NASA has a good site that lets you know when and where to look for it:\nhttp://spaceflight.nasa.gov/realdata/sightings/

There are literally thousands of satellites in orbit capable of both receiving and transmitting radio signals. Some of their names are Telstar, Comsat (Communication satellites), Cosmos 1602, GOES 7, Landsat 5, NOAA 12, Radarsat, and Seasat 1 (weather satellites).

A radio relay station in orbit above the earth that receives, amplifies and redirects analog and digital signals contained within a carrier frequency. There are three kinds. Geostationary (GEO) satellites are in orbit 22,282 miles above the earth and rotate with the earth, thus appearing stationary. The downlink from GEOs back to earth can be localized into small areas or cover as much as a third of the earth's surface.\n\nLow-earth orbit (LEO) satellites reside no more than 1,000 miles above the earth and revolve around the globe every couple of hours. They are only in view for a few minutes, and multiple LEOs are required to maintain continuous coverage. Medium-earth orbit (MEO) satellites are in the middle, taking about six hours to orbit the earth and in view for a couple of hours.\n\nI hope this helps...\n\nDon

Understanding physics has allowed us to launch satellites.  We also know how to make satellites transponders to transmit television signals and know how to calculate the footprint of the transmitted signal.  With world-wide satellite coverage, we never have to go to work.  We can drink beer and watch footy all day long.  Isn't physics great?!

The only satelite images that are on the internet are old images (Google Earth). The only live feeds are observed by government agencies such as NASA, CIA, FBI, etc.

Both Satellite Systems Are Good Better Than Cable You Can Take It With You Any Where And Still Get It! Try Doing That With Cable!

Because most satellites are geosychronous (ie. Follow the earths rotation) a satellite dish can receive and transmit signals just as a you can receive satellite TV. This information is (should be at least) encrypted or scrambled so that only the person/organisation with the key or password can communicate with the satellite. The US have however failed to use this in the past several times and military satellite signals have been known to be able to be received by ordinary citizens given they point their dish in the right position.\n\nFor satellites that are not geosynchronous, ie. imaging satellites that work in a vertical plane such as the ones used by NASA to take pictures of the earth and spy satellites. These satellites are not in constant contact with land - they store their information and then relay it back in the short period of time it is in contact with the base station on earth.\n\nSatellites such as ones that visit Mars and that do not orbit the Earth simply use a higher output signal and a higher gain to receive signals. A larger satellite dish is required to receive these signals, and like the imaging satellites, they are usually not always in contact with earth.\n\nCheers

Get cable or satellite.

satellites.\n\nfor sure

You can find some programs to watch satellite tv for free,but they will have limits.Try tv ants,or satellite for tv.They are good programms with many channels to watch.Special satellite for tv has many many programs.
