Indian Regional Navigation Satellite System

On November 11, India became the fourth country in the world to have its independent regional navigation satellite system recognised by the International Maritime Organisation (IMO) as a part of the World Wide Radio Navigation System (WWRNS).

The navigation system can now replace GPS in the Indian Ocean waters upto 1500 km from the Indian boundary.

The process of getting the recognition for the Indian Regional Navigation Satellite System based on satellites of the Indian Space Research Organisation took about two years.

Merchant vessels in Indian waters can now use the “modern and more accurate” system as an alternative navigation module.
