Summary
IRNSS-1I launched on an Indian Space Research Organization PSLV XL from Satish Dhawan Space Centre First Launch Pad, Satish Dhawan Space Centre, India on April 11, 2018. It was Indian Space Research Organization's 61st launch, 3rd this year and humanity's 5,741st orbital launch attempt. It was the 20th PSLV XL flight and the 2nd this year. The payload was bound for Geosynchronous Transfer Orbit (GSTO). IRNSS-R1I, one of 2 catalogued objects, reached a 277 × 20,655 km orbit inclined 19.2°. 2 objects from this launch are catalogued, one of them a payload.
