India’s Polar Satellite Launch Vehicle, flying in its XL configuration, will launch the IRNSS-1I Navigation Satellite into a sub-Geostationary Transfer Orbit to replenish the country’s Navic Regional Navigation Satellite System. This launch follows up on the 2017 Failure of the PSLV rocket lifting the IRNSS-1H satellite originally intended to replace the first satellite in the seven-satellite constellation which has lost its atomic clocks due to a design flaw and left the system without redundancy. Spiraling up into Geosynchronous Orbit, the satellite will replace IRNSS-1A and restore the constellation to full capacity.
