The Indian Space Research Organisation (IRSO) will launch the IRNSS-1I navigation satellite on April 12from its spaceport in Sriharikota in Andhra Pradesh, which is the eight sat in the NavIC navigation satellite constellation. "The 43rd flight of Polar Satellite Launch Vehicle (PSLV-C41) will launch the Indian Remote Navigation Satellite System (IRNSS-1I) from the first launch pad of the Satish Dhawan Space Centre at Sriharikota on April 12 at 4.04 a.m.," ISRO said. The satellite will weigh 600kg and will have a lifespan of 10 years. The Indian Regional Navigation Satellite System (IRNSS) is an independent regional navigation satellite system developed by India on par with US-based GPS. The navigation satellite will become the eighth such satellite which will join the constellation of Indian navigation satellites also known as the Navigation with Indian Constellation (NavIC) and IRNSS. According to the Times Now, this means that while one of ISRO’s teams is working to re-establish the link with the GSAT-6A satellite, another team is gearing up for the launch the IRNSS-1I navigation satellite that will replace the IRNSS-1A, whose Rubidium atomic clocks, meant to measure precise location data, ceased working almost two years ago. "The upcoming launches like of IRNSS-1I will not be affected because of the snapping of signal link with communication satellite GSAT-6A," Timed of India quoted ISRO chairman Dr K Sivan as saying. As per the report, ISRO tried to launch IRNSS-1H to replace faulty IRNSS-1A on August 31 last year, but the satellite got stuck in the heat shield of the PSLV rocket during the launch.
