Question

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?

Accepted Answer

The Polar Satellite Launch Vehicle (PSLV) is primarily used for launching satellites for Earth observation and remote sensing due to its capability to place payloads into various orbits. The Geosynchronous Satellite Launch Vehicle (GSLV) series, especially the GSLV Mk III, is designed for heavier communication satellites and payloads requiring geostationary transfer orbits. The GSLV Mk III is a three-stage rocket, with its first stage using liquid propellant, the second stage using solid propellant, and the third stage using cryogenic propellant.
