ISRO NavIC Gets IMO Maritime Safety Recognition


  • India became the fourth country in the world to have its independent regional navigation satellite system recognized by IMO.
  • ISRO NavIC has been recognised by the IMO as a component of the World-Wide Radio Navigation System (WWRNS).
  • This latest development will enable the utilisation of ISRO NavIC in the fields of maritime navigation, surveying, and geodesy among others.
  • The Indian GPS-like system is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary.

The Maritime Safety Committee (MSC) of IMO has approved IRNSS (India’s GPS system NavIC) as a World Wide Radio Navigation System (WWRNS), reports Times Now News.

IMO recognition for NavIC

The Indian Space Research Organisation (ISRO) said that the International Maritime Organisation (IMO) has recognised NavIC as a component of the World-Wide Radio Navigation System (WWRNS). This recognition was awarded in the 102nd meeting of Maritime Safety Committee of IMO (MSC-102).

NavIC was represented at IMO by the Directorate General of Shipping (DGS), Ministry of Ports, Shipping and Waterways with technical support from ISRO.

In April 2020, NavIC L5 was incorporated in the Radio Technical Commission for Maritime Services (RTCM) standard 10403.3 for differential Global Navigation Satellite System (GNSS) applications.

Application in maritime navigation

These developments will enable the utilization of NavIC in the fields of maritime navigation, surveying and others.

ISRO has built satellites in the IRNSS series and the constellation is designed to provide accurate position information services within India and the region extending up to 1,500 km beyond its boundary, which is its primary service area.

It is designed to provide two types of services –

  • Standard Positioning Service (SPS), which is provided to all users and
  • Restricted Service (RS), which is an encrypted service provided only to the authorized users.

The system is expected to provide position accuracy of 20 metres or better in the primary service area. The name NavIC was given by Prime Minister Narendra Modi after the successful launch of the seventh navigation satellite, in April 2016.

What is NavIC?

Indian Regional Navigation Satellite System (IRNSS) is called NavIC (which is an acronym for NAVigation with Indian Constellation), is India’s own GPS system, now available on smartphones.

The regional geo-positioning system has been designed in India by ISRO to provide accurate positioning in India and around the Indian mainland. It is said to be more accurate than GPS.

Applications of NavIC chipsets

  • Receivers will provide the users with a satellite-based navigation system
  • Will support 2 Frequency bands for NavIC and GPS respectively
  • Provide active/passive antenna support
  • Enable navigation at sea, on land and in air
  • Help during disasters to track and manage a fleet
  • Enable regular GPS services such as providing location services on phone, maps etc
  • Help trekkers/hikers/travellers in terrestrial navigation
  • Provide for the capture of geodetic data to create maps
  • Provide audio-visual navigation guide for drivers
  • More accurate data created with an understanding of the local terrain
