The first pico satellite of India is:
- A.INSAT
- B.STUDSAT
- C.GSAT-4
- D.ANUSAT
Correct answer
Explanation
The correct answer is B, STUDSAT. STUDSAT, short for Student Satellite, was the first pico satellite built in India. A pico satellite is one that weighs under about one kilogram, and STUDSAT weighed less than that. It was built by students of engineering colleges in Bengaluru and Hyderabad and was launched in 2010 by a PSLV flight as an auxiliary payload, carrying a small camera for imaging the Earth.
Option A, INSAT, is not a single satellite but the Indian National Satellite System, a family of heavy communication satellites in geostationary orbit. Option C, GSAT-4, was an experimental communication satellite that was lost when its launch vehicle failed in 2010. Option D, ANUSAT, was built by Anna University and launched in 2009, but it was a micro satellite of about forty kilograms, not a pico satellite, which is exactly the distinction the question is testing.
