The unnamed chronicler in his Dupin stories was the first Dr. Watson type of satellite—a narrator who accompanies the detective on his exploits, exclaims over his brilliance... .
when used with a larger subwoofer, smaller front left and right main speakers (either physically smaller or set to ÒsmallÓ in multi channel speaker setups) are sometimes referred to as "satellites "  In common use, the term can apply to physically or electronically small rear or surround speakers as well
Any object that orbits a celestial body, such as a moon However, the term is often used in reference to the manufactured objects that orbit the earth, either in a geostationary or a polar manner Some of the information that is gathered by weather satellites, such as GOES9, includes upper air temperatures and humidity, recording the temperatures of cloud tops, land, and ocean, monitoring the movement of clouds to determine upper level wind speeds, tracing the movement of water vapor, monitoring the sun and solar activity, and relaying data from weather instruments around the world
You can refer to a country, area, or organization as a satellite when it is controlled by or depends on a larger and more powerful one. Italy became a satellite state of Germany by the end of the 1930s. Natural object (moon) or spacecraft (artificial satellite) orbiting a larger astronomical body. Most known natural satellites orbit planets; the Earth's Moon is the most obvious example and was the only one known until the discovery of the Galilean satellites of Jupiter in 1610. All the solar system's planets except Mercury and Venus have moons, which vary greatly in size, composition (from rock to mostly ice), and activity (from cold and inert to volcanic). Some asteroids are also known to have their own moons. The first artificial satellite, Sputnik 1, was launched into orbit around Earth in 1957. Since then, thousands have been sent into orbit around Earth as well as the Moon, Venus, Mars, Jupiter, and other bodies. Artificial satellites are used for scientific research and other purposes, such as communication (see communications satellite), weather forecasting, Earth resources management, and military intelligence.

A body which revolves around another body of preponderant mass and which has a motion primarily and permanently determined by the force of attraction of that other body [NTIA] [RR] (188) Note: A parent body and its satellite revolve about their common center of gravity
an electronics retransmission device serving as a repeater, normally placed in orbit around the earth in geostationary orbit for the purpose of receiving and retransmitting electromagnetic signals It normally recedes signals from a single source and retransmits them over a wide geographic area, known as the satellite's "footprint "
