Question

Which Indian satellite was launched that has a fantastic timing and records 1000th of a second?

• A. GSAT-16
• B. IRNSS-1D
• C. GSAT-6
• D. Astrosat

Hint:

It is a 2015 ISRO satellite launched by GSLV-D6.

Answer 1

The Correct Option is C

This question is about Indian satellites launched around 2015 and their special features.

1. GSAT-16: Not correct. GSAT-16 is a communication satellite launched in December 2014 to boost transponder capacity, it is not linked to the fine timing feature in the question.
2. IRNSS-1D: Not correct. IRNSS-1D is part of India's regional navigation system, launched in March 2015, its role is positioning, not the timing feature described here.
3. GSAT-6: Correct. GSAT-6 was launched by ISRO on 27 August 2015 using GSLV-D6. It carried a large unfurlable S-band antenna and precise signal timing and synchronization systems for strategic mobile communication, matching the fine timing described in the question.
4. Astrosat: Not correct. Astrosat, launched in September 2015, is India's first dedicated space observatory for studying celestial objects, not a timing satellite.

So the answer is GSAT-6, option C.
