India: The Indian Space Research Organisation (ISRO) has successfully launched the PSLV-C41/IRNSS-1I. IRNSS-1I is a navigation satellite and the eighth satellite in the constellation. The PSLV-C41/IRNSS-1I Mission kicked off at 04:04 AM ISTon Thursday.
The launch was ISRO’s second endeavour at sending a replacement satellite. The earlier mission of a PSLV carrying IRNSS-1H in August last year failed after the heat shield covering the satellite failed to separate. This also comes two weeks after the space agency launched GSAT-6A on board GSLV Mk-II but the rocket placed GSAT-6A in orbit, ISRO lost communication with the satellite.
RNSS-1I is expected to replace IRNSS-1A, the first of the seven navigation satellites that became dysfunctional after its three rubidium atomic clocks failed. The seven satellites are part of the NavIC navigation satellite constellation.
Previously, the Space Agency said, “India’s Polar Satellite Launch Vehicle, in its forty-third flight (PSLV-C41) in XL configuration will launch IRNSS-1I Satellite from First Launch Pad (FLP) of SDSC (Satish Dhawan Space Centre), Sriharikota.” The ‘XL’ configuration of PSLV is used for the twentieth time. The IRNSS-1I is the eighth satellite to join the NavIC navigation satellite constellation, ISRO added.
