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]
