China launches new GPS rival

China launched the last satellite in its Beidou navigation network on Tuesday, completing a new rival to GPS and cementing its place in an elite group of countries with their own global navigation satellite systems (GNSS).

To date, there are only four major GNSS networks: GPS (US), GLONASS (Russia), Galileo (European Union) and now Beidou. India and Japan operate smaller systems.
Most people are familiar with GPS, which is used for everything from personal navigation on your smartphone to tracking planes and container ships around the world.
Beidou is China's alternative system. It's named after the Chinese word for the Big Dipper constellation, and has taken almost two decades to complete.
In a commentary published Tuesday in the People's Daily, the Chinese Communist Party mouthpiece, the Beidou navigation network was described as belonging "to the whole world and all mankind."
