Learn about how a communications satellite works and how it helps us to connect to each other around the world.
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 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 ...

A satellite is an object that is in orbit around an object in space of a larger size. Things such as the Earth's Moon or Pluto's Charon are natural satellites. Humans have also created artificial satellites—human-made machines and spacecraft in orbit around our Earth or other objects in our galaxy. These types of satellites have fundamentally changed humanity—such as connecting us with ...
