  • ISRO and Antrix are set to commercialise India’s regional navigation satellite system, NavIC.
  • NavIC which essentially means ‘Navigation in Indian Constellation’ is the Indian system of eight satellites that is aimed at telling business and individual users where they are, or how their products and services are moving.
  • It is an indigenous positioning or location based service (LBS) and works just like the Global Positioning System (GPS), but within a 1,500-km radius over the Indian sub-continent.
  • All other global systems like Glonass, GALILEO and Beidou operate on L1 and L2 frequencies. L2 is solely meant for US Defence use.
  • For civilian usage, the new GPS satellites use L5 and L2C band.
  • Navic, being a late-comer could not get allocations in the L1 and L2 bands but was allocated L5 and S bands.
  • NavIC does not have the advantage economies of scale: The success of GPS, which Navic seeks to replace, is due to the enormous volumes of devices that use the service.
  • Some potential applications of the regional navigation system include:
  • Terrestrial, aerial and marine navigation;
  • Disaster management;
  • Vehicle tracking and fleet management;
  • Integration with mobile phones;
  • Precise timing (as for ATMs and power grids);
  • Mapping and geodetic data capture;
  • Terrestrial navigation aid for hikers and travellers;
  • Visual and voice navigation for drivers.
  • Precision surveys
