The PM, Narendra Modi, witnessed the successful launch of the navigational satellite IRNSS-1G from his office, South Block in New Delhi. Isro launched the satellite on board the PSLV-C33 at 12.50pm on Thursday. The PSLV, carrying the satellite, lifted off from Sriharikota at 12.50 PM.

PM witnesses launch of IRNSS-1G; congratulates ISRO scientists through video-conferencing

Moments after the successful launch, the Prime Minister congratulated and addressed the scientists at ISRO in Sriharikota, through video-conferencing. PM Modi declared that this navigation system will be known as NAVIC – “Navigation with Indian Constellation.”

Congrats to all our scientists who worked tirelessly for launch of IRNSS-1G Mission. India salutes your persistence & dedication. A historic day for India’s space programme. 125 crore Indians got a Navic. This is example of  Make in India, made in India and made for Indians. 125 crore Indians have got a new Navic. The benefits from this new technology will benefit our people, our fishermen. The world will know it as Navic: PM Narendra Modi

“With this successful launch, we will determine our own paths powered by our technology. This is a great gift to people from scientists,”

 Know More About Isro’s navigational satellite IRNSS-1G

The Indian Space Research Organisation (Isro) has launched the satellite on board the Polar Satellite Launch Vehicle (PSLV-C33). In its thirty fifth flight (PSLV-C33), ISRO’s Polar Satellite Launch Vehicle successfully launched the 1425 kg IRNSS-1G, the seventh satellite in the Indian Regional Navigation Satellite System (IRNSS) today afternoon (April 28, 2016) from Satish Dhawan Space Centre SHAR, Sriharikota. This is the thirty fourth consecutively successful mission of PSLV and the thirteenth in its ‘XL’ configuration.

IRNSS-1G is the seventh of the seven satellites constituting the space segment of the Indian Regional Navigation Satellite System. IRNSS-1A, 1B, 1C, ID, IE and 1F,  the first six satellites of the constellation, were successfully launched by PSLV on July 02, 2013, April 04, 2014, October 16, 2014, March 28, 2015, January 20, 2016 and March 10, 2016 respectively. All the six satellites are functioning satisfactorily from their designated orbital positions.

IRNSS is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland. IRNSS provides two types of services, namely, Standard Positioning Services (SPS) – provided to all users and Restricted Services (RS) –  provided to authorised users.

IRNSS is expected to provide a positional accuracy of better than 20m in the primary service area. It involves placing three satellites in suitable slots in a geostationary orbit, 35,786km above the Equator, and the remaining four in geosynchronous, elliptical orbits designed to keep the satellites within view of ground stations.

The system will provide two types of services—a Standard Positioning Service for all users and a Restricted Service, an encrypted service for authorized users only.

Some of the applications provided by IRNSS would be terrestrial, aerial and marine navigation, disaster management, vehicle tracking and fleet management, integration with mobile phones, precise timing, mapping and geodetic data capture, terrestrial navigation aid for hikers and travellers, and visual and voice navigation for drivers.
