NAVIC Global

In News 
  • India plans to expand its regional satellite navigation system NaVIC in a bid to increase its use in the civilian sector and also by ships and aircraft travelling far from the country's borders.
NAVIC
  • The Navigation with Indian Constellation (NaVIC) uses seven satellites to provide real-time positioning and timing services in India and an area extending up to 1,500 km from the country's borders.
  • Indian Space Research Organisation (ISRO) plans to replace at least five of these with the improved L-Band, which would enable it to offer better global positioning services to the public as several satellites of the constellation have outlived their lives.
  • The new satellites will have L-1, L-5 and S Band.
  • ISRO has also approached the government for permission to launch an additional 12 satellites in the Medium Earth Orbit (MEO) to expand the reach of NaVIC.
About Navigation satellite 
  • Navigation in Indian Constellation (NavIC) is an Indian Regional Navigation Satellite System (IRNSS), developed by the Indian Space Research Organization (ISRO).
  • IRNSS consists of eight satellites, three satellites in geostationary orbit and five satellites in geosynchronous orbit.
  • The main objective is to provide reliable position, navigation and timing services over India and its neighbourhood.
  • It works just like the established and popular U.S. Global Positioning System (GPS) but within a 1,500-km radius over the sub-continent.
  • It has been certified by the 3rd Generation Partnership Project (3GPP), a global body for coordinating mobile telephony standards.
