Q1. Consider the following statements regarding the DRDO’s indigenous HAPS:
- It is a lighter-than-air platform intended primarily for long-endurance aerial surveillance.
- It was developed by the Aerial Delivery Research and Development Establishment (ADRDE), a DRDO laboratory located in Agra.
- Its operating altitude places it in the thermosphere, where most low-Earth-orbit satellites operate.
- An altitude-control mechanism can form part of its onboard flight-control architecture.
How many of the statements given above are correct?
(a) Only one
(b) Only two
(c) Only three
(d) All four
Answer: (c)
Explanation:
- Statement 1 is Correct: The tested platform is a lighter-than-air stratospheric platform designed for long-endurance surveillance.
- Statement 2 is Correct: ADRDE, Agra, developed the platform.
- Statement 3 is Incorrect: HAPS operates in the stratosphere, not the thermosphere.
- Statement 4 is Correct: Altitude-control mechanisms are among the systems used to maintain the platform's desired operating altitude.
