Telstar, launched in 1962, was the first active communications satellite: it received microwave signals from ground stations and retransmitted them across vast distances back to Earth. Launched in 1960, Echo 1 was designed to explore the new field of communications via space. Its design was remarkably simple: Essentially a large balloon, measuring 30 meters (100 feet) across, the satellite provided a reflective surface in space. Radio signals directed at Echo from one location on Earth "bounced" to another. By the time Echo 2 was launched in 1964, other types of ... This satellite is the heart of a space-based communications system called Iridium.
Conceived, designed, and built by Motorola, the Iridium system provides wireless, mobile communications through a network of 66 satellites in polar, low-Earth orbits. Inaugurated in November 1998, under the auspices of Iridium LLC, this complex space system allowed callers using hand-held mobile phones and ... Launched in April 1965, the International Telecommunication Satellite Organization's Intelsat I (also known as "Early Bird") was the first satellite to provide commercial communications services. Operating in geosynchronous orbit and spin-stabilized, it used a design developed for the earlier Syncom ...
