In 1983, a plan to develop an independent satellite positioning system comprised of two satellites is put forward.
In 1994, the Central Government ratifies the Beidou Satellite Positioning and Navigation system program.
China launches four Beidou system satellites separately on October 31, 2000, December 21, 2000, May 25, 2003, and February 3, 2007. The final successful launch completes China's first-generation geosynchronous satellite positioning and navigation system, which was originally intended to be a regional navigational system.
On April 14, 2007, China launches the navigation satellite Compass M1 into space. It is the first satellite in Beidou's next-generation development, which will upgrades capabilities and range to make it a global positioning and navigation system.
On April 15, 2009, China launches another navigation satellite Compass G2, the second satellite in the Beidou's next-generation development.
By 2020, the Beidou global positioning system program will have its full constellation in place.
