What is a polar orbit used for?
From a polar orbit, a satellite can observe over time anypoint on the globe from directly above it.
What are the four orbit levels for satellite systems?
LEO (Low-Earth-Orbit)-100 to 1000 miles out • Used for wireless e-mail, special mobile telephones, pagers, spying, videoconferencing MEO (Middle-Earth-Orbit)-1000 to 22,300 miles • Used for GPS (global positioning systems) and government GEO (Geosynchronous-Earth-Orbit)-22,300 miles • Always over the same position on earth (and always over the equator) • Used for weather, television, government operations HEO (Highly Elliptical Earth orbit)-satellite follows an elliptical orbit • Used by the military for spying and by scientific organizations for photographing celestial bodies
What does radar and satellite have in common?
I would say they are both highly advanced and are used for tracking things/people but a satellite is more advanced with being able to live in and what not
How much does it cost to send a satellite in to space from earth to space?

What is the technology used in live telecast?
A communications satellite (sometimes abbreviated to COMSAT) is an artificial satellite stationed in space for the purpose of telecommunications. Modern communications satellites use a variety of orbits including geostationary orbits, Molniya orbits, other elliptical orbits and low (polar and non-polar) Earth orbits. For fixed (point-to-point) services, communications satellites provide a microwave radiorelay technology complementary to that of submarine communication cables. They are also used for mobile applications such as communications to ships, vehicles, planes and hand-held terminals, and for TV and radio broadcasting, for which application of other technologies, such as cable, is impractical or impossible. A direct broadcast satellite is a communications satellite that transmits to small DBS satellite dishes (usually 18 to 24 inches or 45 to 60 cm in diameter). Direct broadcast satellites generally operate in the upper portion of the microwave Ku band. DBS technology is used for DTH-oriented (Direct-To-Home) satellite TV services, such as DirecTV and DISH Network in the United States, Bell TV and Shaw Direct in Canada, Freesat in the UK and Sky Digital in the UK, the Republic of Ireland, and New Zealand.
