SRIHARIKOTA, India (ISRO PR) — Geosynchronous Satellite Launch Vehicle-F10 (GSLV-F10) will launch Earth Observation Satellite, EOS-03 from the Second Launch Pad of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch is tentatively scheduled at 0543 Hrs IST [0013 UTC] on Thursday, Aug. 12 [08:13 p.m. EST on Wednesday, Aug. 11], subject to weather conditions.

EOS-03 is a state-of-the-art agile Earth observation satellite which will be placed in a Geosynchronous Transfer Orbit by GSLV-F10. Subsequently, the satellite will reach the final geostationary orbit using its onboard propulsion system.

A 4 metre diameter Ogive shaped payload fairing is being flown for the first time in this GSLV flight. This is the fourteenth flight of GSLV.
