ISRO completes NavIC constellation with IRNSS-1I

The Indian Space Research Organisation (ISRO) launched the IRNSS-1I under its regional navigation satellite system — also called NavIC — adding to the constellation of six operational satellites. The seven satellites are part of the NavIC navigation satellite constellation.

The Indian Space Research Organisation (ISRO) thus completed the constellation, which needed seven functional satellites to provide foolproof satellite-based navigation signals.

  • Serving both military and civilian needs, the Regional Navigation Satellite System, also called NavIC, will broadcast highly-accurate timing signals that a receiver can use to triangulate its location.
  • IRNSS-1I is expected to replace IRNSS-1A, the first of the seven navigation satellites, that was rendered ineffective after its three rubidium atomic clocks failed.

About NavIC navigation satellite constellation :-

The NavIC system enables providing position, navigation and timing information that could be utilised for a large range of civil and strategic applications and services that include

  • Terrestrial, aerial and marine navigation
  • Precise timing
  • Disaster management and alert messages.
  • Mapping and Geodetic data capture
  • vehicle tracking and fleet management
  • Visual & voice navigation for drivers.

The constellation will also provide signals in a space covering India and its surroundings, which could be utilised by using receivers on ground to determine position and time accurately.
