Why in news
- ISRO successfully placed EOS-05 into geosynchronous orbit from where it will operate 36,000 km above Earth.
- EOS-05 is India's first geosynchronous earth observation satellite designed for continuous broad-area monitoring.
Key terms
Geosynchronous Orbit
An orbit matching Earth's rotational period, allowing a satellite to remain fixed above a specific longitude.
Low Earth Orbit (LEO)
Orbits at altitudes between 160 km to 2,000 km, providing high-resolution images but short revisit times.
What is EOS-05?
- A specialized Earth Observation Satellite stationed in Geosynchronous Equatorial Orbit (GEO) at an altitude of approximately 36,000 km.
- Unlike Low Earth Orbit (LEO) imaging satellites that pass periodically, a GEO observation platform provides near-continuous stationary coverage over a specific geographic footprint.
Key Capabilities and Applications
- Enables persistent real-time monitoring of strategic assets, border regions, and maritime conflict zones.
- Supplies continuous high-cadence environmental and disaster management monitoring over the Indian subcontinent.
Why it matters
- Fills a crucial gap in space-based surveillance by complementing intermittent LEO imagery with continuous GEO observation.
- Enhances national defense, border monitoring, and rapid disaster response operational readiness.
Prelims facts
- EOS-05 is placed in geosynchronous orbit (~36,000 km), not Low Earth Orbit.
- Geosynchronous observation allows persistent real-time monitoring of a fixed region.
Mains discussion
- Strategic significance of indigenous space assets in national border security and disaster mitigation.
