BeiDou Navigation Satellite System

The BeiDou Navigation Satellite System (BDS, ) is a Chinese satellite navigation system. It consists of two separate satellite constellations – a limited test system that has been operating since 2000, and a full-scale global navigation system that is currently under construction.
The first BeiDou system, officially called the BeiDou Satellite Navigation Experimental System () and also known as BeiDou-1, consists of three satellites and offers limited coverage and applications. It has been offering navigation services, mainly for customers in China and neighboring regions, since 2000.
The second generation of the system, officially called the BeiDou Satellite Navigation System (BDS) and also known as COMPASS or BeiDou-2, will be a global satellite navigation system consisting of 35 satellites, and is under construction . It became operational in China in December 2011, with 10 satellites in use, and began offering services to customers in the Asia-Pacific region in December 2012. It is planned to begin serving global customers upon its completion in 2020.
According to China daily. Fifteen years after the satellite system was launched, it is now generating $31.5 billions for major companies such as China Aerospace Science and Industry Corp, AutoNavi Holdings Ltd, and China North Industries Group Corp.〔http://www.chinadaily.com.cn/bizchina/tech/2015-11/16/content_22464083.htm〕
==Nomenclature==
The official English name of the system is ''BeiDou Navigation Satellite System''.〔(English Name of BeiDou )〕 It is named after the Big Dipper constellation, which is known in Chinese as ''Běidǒu''. The name literally means "Northern Dipper", the name given by ancient Chinese astronomers to the seven brightest stars of the Ursa Major constellation. Historically, this set of stars was used in navigation to locate the North Star Polaris. As such, the name BeiDou also serves as a metaphor for the purpose of the satellite navigation system.
