The Beidou Satellite Navigation System (BDS) is a self-established global satellite navigation system (GNSS) developed by China. It is the third mature satellite navigation system after the United States Global Positioning System (GPS) and the Russian GLONASS Navigation System (GLONASS) System, together with GPS, GLONASS and the Galileo system under construction in Europe, form the four major global satellite navigation systems for some time to come and have been identified by the United Nations Satellite Navigation Commission as suppliers since December 26, 2012. The BDS China and the surrounding areas to provide services, positioning accuracy of 10 m, speed accuracy of 0.2 m / s,
