Isro’s GSLV-F17 successfully places EOS-05 Earth observation satellite in geosynchronous orbit
The Indian Space Research Organisation (ISRO) successfully launched the EOS-05 Earth observation satellite into a geosynchronous orbit using the GSLV-F17 rocket. This mission marks a milestone for India, as it is the country's first imaging satellite specifically designed for this high-altitude orbit.
Why it matters
This launch enhances India's strategic Earth observation capabilities and demonstrates the increasing payload capacity and technical maturity of the GSLV launch vehicle program.
SRIHARIKOTA: The Indian Space Research Organisation (Isro) successfully launched EOS-05, India’s first imaging satellite designed to operate from a geosynchronous orbit, aboard GSLV-F17 in the early hours of Friday.The 51.7-metre-tall, 420.5-tonne, three-stage rocket lifted off from the second launch pad at Sriharikota at 2.55am and placed the around 2,367kg Earth observation satellite in its intended sub-geosynchronous transfer orbit.This was the 19th GSLV flight. GSLV-F17 had a S139 solid core with four L40H liquid strap-ons, a GL40HT liquid second stage and a CUS15 indigenous cryogenic upper stage, besides a four-metre composite ogive payload fairing.EOS-05 was injected into a geosynchronous transfer orbit. It will eventually achieve a nominal perigee of 170km, apogee of 28,934km and inclination of 19.28 degrees. The satellite will be moved to the final orbit through a series of manoeuvres using onboard thrusters.Isro chairman V Narayanan said the rocket injected the satellite in the intended orbit precisely.
