What is a satellite made out of?
A: There are a wide variety of materials used for either, but satelites are usually made to be etremely light weight, and use materials such as titanium and alluminum. Addidtionally, they'll use composites and alloys, such as nickel-cadmium or aluminum-beryllium.
Artificial satellites. An artificial satellite is an object that people have made and launched into orbit using rockets. There are currently over a thousand active satellites orbiting the Earth. The size, altitude and design of a satellite depend on its purpose.
- Many authors define "satellite" or "natural satellite" as orbiting some planet or minor planet, synonymous with "moon"—by such a definition all natural satellites are moons, but Earth and other planets are not satellites.
- The basic satellite dish consists of the following materials: A parabolic reflector made of fiberglass or metal, usually aluminum, with a protruding steel feed horn and amplifier in its middle. A steel actuator that enables the dish to receive signals from more than one satellite.
- Satellites orbit Earth at different heights, different speeds and along different paths. The two most common types of orbit are "geostationary" (jee-oh-STAY-shun-air-ee) and "polar." A geostationary satellite travels from west to east over the equator.

- (Cable TV companies work on the same principle.) At the broadcast center, the TV provider receives signals from various programming sources and beams a broadcast signal to satellites in geosynchronous orbit. The satellites receive the signals from the broadcast station and rebroadcast them to Earth.
- The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter. A satellite receiver then decodes the desired television programme for viewing on a television set. Satellite television provides a wide range of channels and services.
- To access the Signal Meters menu:
- Press the menu button on your remote.
- Select Settings and Help on the left hand menu.
- Select Settings.
- Select Satellite on the left hand menu.
- Select View Signal Strength on the bottom right-hand screen (scroll to it using the arrows on your remote).
Space stations and human spacecraft in orbit are also satellites. Satellite orbits vary greatly, depending on the purpose of the satellite, and are classified in a number of ways. Well-known (overlapping) classes include low Earth orbit, polar orbit, and geostationary orbit.

- Orbital velocity is the speed needed to stay in orbit. So really, a satellites ability to maintain its orbit comes down to a balance between two factors: its velocity (or the speed at which it would travel in a straight line), and the gravitational pull between the satellite and the planet it orbits.
- This means that they stay in a fixed position over the Earth's surface. Geostationary satellites have uses such as: communications - including satellite TV. global positioning or GPS - which is used for sat navs (satellite navigation systems)
