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.
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.
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.
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.
the earth spinds around the sun because gravity makes it orbit
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

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.
The answer is yes because as it orbits countinously it accelerates by moving in a different direction and someti,es in a different velocity.
Yes, satellites at different heights can have equal velocities if they are in circular orbits with the same period. In this case, the satellite at a higher altitude will have a slower velocity than the satellite at a lower altitude, but their velocities will be equal at any given point in their orbits.

He used the reflecting telescope and calculus to map the orbits of planets and 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.
Yes, artificial satellites orbit the Earth in different orbits depending on their purpose, such as communication, weather monitoring, or scientific research. These satellites are launched into space and carefully positioned to ensure stable and productive operations.
