પ્રિલિમ્સ ટ્રેપ
GISAT-1A is a Low Earth Orbit satellite providing global coverage every 30 minutes.
Aspirants often confuse GISAT's Geostationary Orbit (GSO) with Low Earth Orbit (LEO) or Sun-Synchronous Orbit (SSO) used by standard IRS missions.
સંલગ્ન સ્થિર ખ્યાલો
What are the primary differences between Low Earth Orbit (LEO) and Geosynchronous Orbit (GSO) satellites used in Earth observation?
- Orbit Altitude: Altitude range, operating below 2,000 km for LEO and precisely at 35,786 km for GSO/GEO.
- Coverage Style: Coverage type, where LEO provides global swaths with revisit times of days, while GSO provides continuous real-time staring over a fixed regional sector.
- Vehicle Demand: Launch complexity, requiring heavier launch vehicles like GSLV for GSO payloads compared to lighter PSLV or SSLV for LEO missions.

With reference to India's satellite launch vehicles, consider the following statements: 1. PSLVs launch the satellites useful for Earth resources monitoring whereas GSLVs are designed mainly to launch communication satellites. 2. Satellites launched by PSLV appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth. 3. GSLV Mk III is a four-staged launch vehicle with the first and third stages using solid rocket motors; and the second and fourth stages using liquid rocket engines. Which of the statements given above is/are correct?
