Model Answer

Earth observation satellites provide remote-sensing information about the Earth’s surface, atmosphere and oceans. EOS-05, launched aboard GSLV-F17, is India’s first imaging satellite designed for geosynchronous orbit, enabling persistent observation of the Indian region.

Why EOS-05 is significant

1. Geosynchronous orbit enables repeated observation of the same geographical region.
2. It complements Low Earth Orbit satellites, which provide detailed imagery but have periodic revisit gaps.
3. Persistent imaging improves near-real-time situational awareness.
4. Advanced imaging strengthens India’s indigenous remote-sensing capabilities.

Major applications for India

1. Disaster management improves through rapid monitoring of cyclones, floods and forest fires.
2. Agricultural monitoring supports assessment of crops, vegetation and soil conditions.
3. Environmental surveillance helps track land-use and ecological changes.
4. Maritime observation improves monitoring of India’s surrounding oceanic region.
5. Persistent observation strengthens strategic surveillance and national security.

Way Forward

1. Integrate EOS-05 data with existing Earth observation and disaster-management platforms.
2. Develop AI-based analytics for rapid interpretation of satellite imagery.
3. Expand indigenous sensors and a complementary multi-orbit Earth observation constellation.

EOS-05 represents a shift from periodic observation towards persistent Earth monitoring, strengthening India’s capacity for informed governance, disaster preparedness and strategic situational awareness.
