New geosynchronous ‘eye in the sky’ promises faster disaster monitoring, environmental tracking, and strategic surveillance.
ISRO successfully launched the EOS‑05 Earth observation satellite aboard the GSLV‑F17 rocket on September 4, 2026. It is placed in a Sub‑Geosynchronous Transfer Orbit before it begins raising itself to its final 36,000‑km geosynchronous position.
Once operational, EOS‑05 will become India’s first imaging satellite from geosynchronous orbit, enabling persistent observation of large regions — something low‑Earth‑orbit satellites cannot provide.
Its high‑frequency imaging will be crucial for monitoring rapidly evolving events such as cyclones, floods, forest fires, and cloud formations, offering updates as frequently as every 30 minutes under suitable conditions. The satellite will also support agriculture, environmental monitoring, and multispectral analysis to detect changes in vegetation, soil, and land conditions.
Multispectral and hyperspectral imaging can provide information that goes beyond what the human eye sees in a convention. EOS‑05 strengthens India’s ability to observe sensitive borders and maritime regions through persistent surveillance.
The mission also redeems the GISAT‑1 setback from 2021.
