  • The Indian Regional Navigation Satellite System (IRNSS) has been accepted as a component of the World-Wide Radio Navigation System by the International Maritime Organisation (IMO) for its operation in the Indian Ocean Region.
  • This will enable the vessels to use IRNSS to obtain position information similar to GLONASS and GPS.
  • The navigation system up to 1,500 km in the Indian Ocean waters can now replace GPS.
  • The operational name of IRNSS is NavIC.
  • It has eight constellations in its orbit.
  • However, IRNSS is only a regional navigational system and not a global navigational system.
  • India has now become the fourth country in the world to have independent regional satellite navigation system after US, Russia and China.
  • The IMO is an organization of the United Nations.
