A satellite is an artificial object that is deliberately sent into orbit in space, usually in order to send, receive or bounce back information to different areas of Earth. Artificial satellites are man-made satellites, they differ to natural satellites such as the Moon which orbits Earth and Earth itself which orbits the Sun.
The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense.GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. Each satellite is built to last about 10 years. 2  Replacements are constantly being built and launched into orbit. 3  A GPS satellite weighs approximately 2,000 pounds and is about 17 feet across with the solar panels extended. 4  Transmitter power is only 50 Watts or less.
