Indian Regional Navigation Satellite System (IRNSS) is an independent regional navigation satellite system being developed by Indian Space Research Organization (ISRO).

In May 2013, India decided to develop its own standards for navigation to usher in a new era in terrestrial, aerial and marine navigation services. During 2014, ISRO delivered the same and launched the IRNSS 1C on board ISRO’s PSLV C26 rocket.

IRNSS was built to offer an alternative to the American GPS or Global Positioning System that is widely, used by consumers on mobile phones to mapping giants and even the military to triangulate location.

It 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, which is its primary service area. An Extended Service Area lies between primary service area and area enclosed by the rectangle from Latitude 30 deg South to 50 deg North, Longitude 30 deg East to 130 deg East.

IRNSS will provide two types of services, namely,

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

The IRNSS System is expected to provide a position accuracy of better than 20 m in the primary service area. The space segment consists of the IRNSS constellation of seven satellites.

According to Deviprasad Karnik, the director, publication and public relations, ISRO the project is heading towards being operational by the middle of 2016.   The Indian Space Research Organisation has unveiled plans to gradually make its regional satellite navigation system global — akin to powerful position-telling systems such as USA GPS and the Russian GLONASS.

It's time to move away from the American Global Positioning System (GPS) and make way for India's own desi navigation system — IRNSS on the mobile phones.
