About BeiDou Navigation System (BNS)

  • BNS is 2nd generation of the Chinese navigational system seen as rival to the US’s Global Positioning System (GPS).
  • The system comprises total 35 satellites in two separate satellite constellations (i) Limited test system (operational since 2000) (ii) A full-scale global navigation system which is currently under construction.
  • The BNS became operational in December 2011 in China with the constellation of 10 satellites of the system.
  • In December 2012, the system began offering services to customers in the Asia-Pacific region. On its completion in 2020, the system will provide services to global customers.
  • After completion, the navigaton system would become an equivalent of the US Global Positioning System, Europe’s Galileo and Russia’s Glonass.
  • Applications: (i) Civilian services: Navigation, messaging, transportation and weather forecasting sectors. (ii) Military applications: Ensure privacy for its military communications and missile launches by reducing the dependence on US operated GPS.
