About this launch
GISAT-1A (EOS-05) launched on an Indian Space Research Organization GSLV Mk. II from Satish Dhawan Space Centre Second Launch Pad, Satish Dhawan Space Centre, India on September 3, 2026 at 21:25 UTC. The launch window ran from 21:00 to 01:00 UTC. It was Indian Space Research Organization's 100th launch, 2nd this year and humanity's 7,383rd orbital launch attempt. It was the 13th GSLV Mk. II flight and the 1st this year. The payload was bound for Geostationary Transfer Orbit (GTO). It reached a 159 × 30,974 km orbit inclined 19.3°.
GISAT-1A (GEO Imaging Satellite) is an Indian earth observing satellite operating from geostationary orbit to facilitate continuous observation of Indian sub-continent, quick monitoring of natural hazards and disaster. EOS-05/GISAT-1A will replace EOS-03/GISAT-1 lost in launch failure in 2021.
