આ શા માટે મહત્વનું છે

Highlights India's advancements and resilience in space technology, addressing mission setbacks and resuming critical earth observation capabilities for national security and disaster management.

સારાંશ

ISRO is set to end its seven-month operational hiatus caused by a January launch vehicle failure with the scheduled September launch of the GISAT-1A Earth observation satellite. GISAT-1A will provide continuous, real-time imaging of the subcontinent, boosting India's disaster management and strategic monitoring capabilities.

મુખ્ય મુદ્દા

  • ISRO faced a seven-month operational hiatus following a launch vehicle debacle in January.
  • The upcoming launch of the GISAT-1A Earth observation satellite in September marks the resumption of ISRO's operational missions.
  • GISAT-1A is a crucial geo-imaging satellite designed for real-time observation of the Indian subcontinent, disaster management, and strategic surveillance.

GISAT-1A is a traditional Low Earth Orbit (LEO) remote sensing satellite that provides periodic global imaging.

Aspirants often confuse GISAT-1A's geosynchronous orbit with Low Earth Orbit (LEO) remote sensing satellites. GISAT-1A provides continuous real-time imaging from a 36,000 km altitude, unlike LEO satellites which offer periodic coverage.

Science & Technology Space Technology

What are the key differences between Low Earth Orbit (LEO) and Geosynchronous Orbit (GEO) satellites used in remote sensing?

  • Altitude & Coverage: LEO satellites operate at lower altitudes (160-2,000 km) providing high-resolution periodic coverage, whereas GEO satellites operate at 36,000 km for continuous, real-time monitoring of a fixed region.
  • Primary Applications: LEO is ideal for global mapping and detailed resource surveys, while GEO is crucial for meteorology, continuous disaster tracking, and real-time strategic surveillance.

  • Geo-imaging satellites and disaster management frameworks

    Geostationary Earth observation satellites combine space tech with Internal Security (border surveillance) and Disaster Management (NDMA guidelines on real-time cyclone tracking).

GISAT-1A's geosynchronous orbit advantage over LEO satellites for real-time disaster tracking is a prime UPSC statement-trap.
