The Polar Satellite Launch Vehicle, in its thirty-fifth flight (PSLV-C33), launches IRNSS-1G, the seventh satellite of the Indian Regional Navigation Satellite System (IRNSS) into a Sub-Geosynchronous Transfer Orbit (Sub-GTO). The launch took place from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota on April 28, 2016. As in the previous six launches of IRNSS satellites, PSLV-C33 uses ‘XL’ version of PSLV equipped with six strap-ons, each carrying 12 tons of propellant.

The ‘XL’ configuration of PSLV is used for the thirteenth time. Besides launching six IRNSS satellites, PSLV-XL has also launched many other spacecraft including India’s Mars Orbiter spacecraft, the multi-wavelength observatory ASTROSAT, Radar Imaging satellite RISAT-1 and the Communication satellite GSAT-12. This apart, PSLV-XL has successfully placed five satellites from United -Kingdom into orbit in a single commercial mission.
This is the thirty-fourth consecutively successful mission of PSLV, repeatedly proving its reliability and versatility.
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. A number of ground facilities responsible for satellite ranging and monitoring, generation and transmission of navigation parameters, etc., have been established in eighteen locations across the country. Today’s successful launch of IRNSS-1G, the seventh and final member of IRNSS constellation, signifies the completion of the IRNSS constellation.
Honourable Prime Minister of India, Mr. Narendra Modi, heartily thanked and congratulated all the ISRO scientists and team ISRO for completing IRNSS constellation and dedicated IRNSS to the nation as ‘NavIC’ (Navigation Indian Constellation). He appreciated India’s space community for making the country proud through such achievements which have helped in improving the life of common man.
Spationet community congratulates Indian scientists for achieving this milestone.
