What is a Satellite?
A satellite is basically any object that revolves around a planet in a circular or elliptical path or orbit. The moon is Earth’s original, natural satellite, and there are many manmade (artificial) satellites, their orbits are usually closer to Earth. Satellite service is the only broadband technology that is able to reach virtually any part of the United States. Television viewers are familiar with the concept of satellite dishes that receive TV channels. It can be used to carry phone calls, and radio signals, as well as video programs and internet service, which require more bandwidth and are within the category of communications services called broadband services. Other broadband data is delivered in exactly the same way. For many rural areas of the United States, and especially Alaska, satellite service is the only way that residents and businesses will ever have access to the Internet and to other broadband services. Satellite is currently the most expensive way to deliver telecom

A satellite is an object that goes around, or orbits, a larger object, such as a planet. While there are natural satellites, like the moon, hundreds of man-made satellites also orbit the Earth. Back to Top What are the components of a human-made satellite? • communication capabilities with Earth • a power source • a control system to accomplish its mission Communications antennae, radio receivers and transmitters enable the satellite to communicate with one or more ground stations, called command centers. Messages sent to the satellite from a ground station are “uplinked”; messages transmitted from the satellite to Earth are “downlinked.” Many satellites are powered by rechargeable batteries, taking advantage of the ultimate battery charger, the sun. Silvery solar panels are prominent features on many satellites. Other satellites have fuel cells that convert chemical energy to electrical energy, while a few rely on nuclear energy. Small thrusters provide attitude, altitude, and propuls
A satellite can be defined as any object, either manmade or naturally occurring, that orbits around something else. For example, the moon orbits around Earth and is thus a satellite. The Earth orbits around the sun and is a satellite of the sun. Other examples of naturally occurring satellites include comets, stars, asteroids, and other planets. Orbit is determined by the gravitational pull of the object around which the satellite circles. The thing around which a satellite circles is called the primary object. However, primary objects are also affected by their satellites, and feel some of their gravitational pull. In some cases, when two objects have a similar size and weight (mass), and a similar gravitational pull, they may be called binary systems, rather than being called a primary object and a satellite. Some argue that Pluto’s moon Charon, and Pluto, represent a binary system instead of a primary object and satellite, since both have similar mass. Most are more familiar with th
