... As a global satellite navigation system, the BeiDou system aims to provide all-day and all-weather navigation services of high performance and reliability for users around the world, with regional passive services coverage by 2012 and global passive services coverage by 2020. The BeiDou system adopts four basic principles of openness, independence, compatibility, and gradualness.

... In disaster prevention and mitigation, the BeiDou system can help to improve rescue response and decision-making capability through broadcasting rapid and timely disaster alerts, scheduling rescue commands, and providing rapid emergency communication. Especially during the Southern China snowstorm and the earthquakes in Wenchuan, Sichuan Province, and Yushu, Qinghai Province, BeiDou terminals sent the disaster and rescue information to a command center in the first place and provided strong support to the search and rescue work.
