GSLV-F17 launches EOS-05, India’s first imaging satellite for geosynchronous orbit
Key facts
- On 4 September 2026, GSLV-F17 launched the 2,367-kg EOS-05 satellite from Sriharikota.
- EOS-05 is India's first imaging satellite designed to watch Earth from geosynchronous orbit, about 36,000 km up.
- It is the heaviest satellite a GSLV has launched so far.
- It was ISRO's first launch since the PSLV-C62 failure in January 2026.
Why it matters
[First] A satellite in geosynchronous orbit can keep watching the same region. That helps disaster management, farming and strategic monitoring. Most imaging satellites fly in low orbits and pass over an area only now and then.
