ISRO's IRNSS-1G-India's Seventh Navigation Satellite Launched Successfully

BENGALURU: The Indian Space Research Organization (ISRO) has successfully launched IRNSS-1G navigation satellite, India’s seventh and the last navigation satellite of the Indian Regional Satellite System (INRSS) series. The onset of INRSS is to deliver indigenously developed accurate GPS service to Indian users as well as for the defense purposes, reports Financial Express.

PSLVC33 that carried IRNSS was launched on April 28, 2016 from the spaceport of Sriharikota in Andhra Pradesh. Here are the six significant facts that one must know about ISRO’s IRNSS.

1. IRNSS comprising of seven satellites would be able to provide navigation system with much better accuracy and targeted position. Three satellites of IRNSS that are inclined at 5 degrees are named GEO satellites. Three of these satellites are installed at 32 degrees E, 83 degrees E and 131.5 degrees E. While the remaining four GSO satellites are installed in inclined orbit with longitude crossover of equatorial plane at 55 degrees E and 111.75 degrees E. These GSO satellites are positioned in two planes with the planes being 180 degrees apart.

2. To its credit, ISRO had launched the sixth navigation satellite IRNSS-1F on March 10, the other five being IRNSS-1A on July 1, 2013, IRNSS-1B (April 4, 2014), IRNSS-1C (October 16, 2014), IRNSS-1D (March 28, 2015) and IRNSS-1E (January 20, 2016).

3. ISRO officials estimated that the total cost of all the seven satellites was Rs 1,420 crore. The IRNSS system coverage region extends up to 1,500 km from its boundary. This service area is between primary service, and area is surrounded by a rectangle from Latitude 30 degree South to 50 degree North, Longitude 30 degree East to 130 degree East. The IRNSS claims to deliver position accuracy of better than 20 meters in the primary service area.

4. The PSLV-C33, carrying IRNSS-1G, in its 35th flight, would be the XL variant that was used during the launch of Mars Orbiter Mission, Chandrayaan-1, ASTROSAT besides the six IRNSS satellites.

5. Having a 12 year mission life, the 44.4 meter tall IRNSS-1G weighs 1,425 kg and would be launched in sub-Geosynchronous Transfer Orbit (sub GTO).

6. With the launch and operationalization of IRNSS-1G which is the seventh in constellation, the completion of IRNSS constellation will be achieved, ISRO said.
