The Compass Navigation Satellite System (CNSS), also named BeiDou-2, is China’s second-generation satellite navigation system capable of providing positioning, navigation, and timing services to users on a continuous worldwide basis.
On November 2, 2006, China announced the 2nd generation Chinese navigation system, COMPASS<ref>[http://en.wikipedia.org/wiki/Compass_navigation_system COMPASS Navigation system in Wikipedia]</ref>. The system is currently under development evolving from a regional system called BeiDou-1, and in the first phase will provide high-accuracy positioning services for users in China and its neighbouring regions. As of April 2011, eight satellites for Compass have been launched. According to an official report<ref name="Compass-IGSO3">[http://business.globaltimes.cn/industries/2011-04/642763.html ''China completes basic Beidou (Compass) Navigation Satellite System''], 2011-04-10 by Globaltimes.cn</ref>, " ''the eighth Beidou/Compass satellite marks the completion of basic function of Beidou (Compass) Navigation Satellite System'' " .
The long-term goal is to develop an independent ''global'' navigation satellite system similar to the GPS and GLONASS.<ref name=Chinese_today>[http://www.sinodefence.com/space/spacecraft/beidou2.asp Compass on the Chinese Defence Today website] </ref>

The BeiDou Navigation Satellite System (BDS), also known as BeiDou-2[1], is China’s second-generation satellite navigation system[1][2] that will be capable of providing positioning, navigation, and timing services to users on a continuous worldwide basis[3].


As for the other GNSSs, the main layers of BeiDou architecture are:

  • BeiDou Space Segment: By 2020, the space segment will consist of a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 non-GSO satellites; 27 in Medium Earth Orbit (MEO) and 3 in Inclined Geosynchronous Orbit (IGSO). The constellation has been designed in order to provide a worldwide coverage[4].
  • BeiDou Ground Segment: The components of the ground segment include a Master Control Station, Upload Stations and several Monitor Stations.[4]
  • BeiDou User Segment: The User Segment is composed of the BeiDou user terminals, which receive BeiDou navigation signals, determine pseudoranges (and other observables) and solve the navigation equations in order to obtain their coordinates. There is also an international cooperation in terms of Compatibility and Interoperability between BeiDou and other GNSSs, that will lead to terminals compatible with other GNSSs.[4]
