Why do satellites have different aerials and positional orbits?
Wiki User
∙ 14y ago
Satellies have different aerials and positional orbits due to the molecular gravitional pull of the moon and the Earth's surface. The use of the aerials in the satellites assist in the communication between the microwave fields of the transmission towers.

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.
How high do GPS satellites orbit?
24 -Physics for Science and Engineers Tipler and Mosca Page 84answ2. A constellation of satellites is usually 24 plus a few spares to allow for mishaps.There is the Navstar GPS set, there is a Russian named Glonass, The Chinese are well through completing their set, and the European Union has made a start on Galileo.From all of these one may obtain GPS data, and all operate in closely similar manners and frequencies for rather obvious inter-operability reasons.
What is the difference between a aircraft and a satellite?
A satellite is generally something that orbits another, such as the moon, and an aircraft is, for the most part, used in the lower parts of the atmosphere, and usually contain one or more passengers.
How does the earth spin around the sun?
the earth spinds around the sun because gravity makes it orbit
What are three things that computers are used for by space engineers?
1: to calculate and control orbits in space. 2: to decipher coded messages (as was in WWII) 3: to control the flight while working with the ground computers 4: to gather and analyze data while in flight
Why communication satellites have different aerials and positional orbits'?
yew
Satellites have different aerials and positional orbits?
Satellites have different aerials and orbits in order to ensure they do not collide or send mixed signals. Satellites are a vital part to the advancement of technology in the world.
Are satellites an example of acceleration as it countinously orbits the earth?
The answer is yes because as it orbits countinously it accelerates by moving in a different direction and someti,es in a different velocity.
What are the 2 orbits of satellites?
Artificial and natural satellites. Artificial satellites are man-made satellites sent into space for a variety of different purposes e.g. taking pictures of the earth for scientific investigation Natural satellites are moons, which orbit planets and are not man-made.
What are the suns satellites?
A satellite is an object that orbits a planet. The Sun is a star so it does not have satellites. Actually a satellite is anything that orbits another. So the planets and asteriods are the sun's satellites.
Satellites with orbits revolve around earth?
no
Satellites with what orbits around earth?
moon
What tool did Sir Isaac Newton use to map the orbits or plantes and satellites?
He used the reflecting telescope and calculus to map the orbits of planets and satellites.
What are the types of satellites orbits?
There are basically three types of orbits.* Sun Synchronous Orbits * Polar Orbits * Geosynchronous Orbits There are variations on these types. Visit related link below.
Are all satellites moons?
A satellite is an object, man made or natural, that orbits something else. No, not all satellites are moons, but all moons are satellites; they're natural satellites.
What planet has no satellites and a retrograde revolution?
Venus has no natural satellites and retrograde motion (orbits opposite direction it rotates).
A short note on Man Made Satellites?
satellites are those which orbits any planet such as earth.The benifits of satellites are we can know about the things happing on the earth.
