ISRO’s 51.7-Metre Giant Gets Ready to Put India’s Eye in the Sky
EOS-05 will provide continuous imagery of the Indian subcontinent and support border monitoring, weather tracking and fire detection, ISRO said.
- The Indian Space Research Organisation will launch the EOS-05 Earth observation satellite from Sriharikota at 2.55am on Friday, marking ISRO's first flight in nearly eight months.
- EOS-05 represents a renewed effort after the earlier GISAT-1 mission failed during launch five years ago due to a technical problem with the GSLV-F10 rocket's cryogenic upper stage.
- Unlike Cartosat or RISAT series satellites operating in low Earth orbit at altitudes around 60 km to 2,000 km, EOS-05 will operate from a geosynchronous orbit about 36,000 km above Earth.
- This position enables a persistent view of the Indian subcontinent, useful for tracking severe weather, fires, and border changes; the satellite carries two instruments with 42 metres per pixel resolution.
- ISRO describes the satellite as India's first state-of-the-art imaging platform in geosynchronous orbit, intended for both civilian and strategic applications including detailed Earth monitoring and environmental tracking.

India’s first imaging satellite in geosynchronous orbit lifts off successfully
While several earth observation satellites operate from low earth orbit (LEO), the EOS-5 satellite is set to hover at an altitude of roughly 36,000 km above earth, which is the geosynchronous orbit and at that level, the satellite will match Earth's rotational speed.
ISRO launched the EOS-05, also known as GISAT-1A, satellite on September 4, 2026, aboard a GSLV-F17. It will take images of India every 30 minutes from an altitude of 36,000 kilometers. This mission is crucial for disaster management and agricultural monitoring.
ISRO to launch GSLV EOS-5 Earth observation satellite tonight
ISRO will attempt the launch of the ‘Naughty Boy’ Geosynchronous Satellite Launch Vehicle, or GSLV-F17, from the Second Launchpad at Sriharikota to deploy EOS-5, India's first Earth Observation Satellite to operate from geosynchronous orbit, 36,000 kilometres above India.
