Explanation:

• Pune-based Giant Metre wave Radio Telescope (GMRT) has become the third Indian scientific facility to be awarded the Institute of Electrical and Electronics Engineers (IEEE) milestone for its novel engineering, advanced technology and scientific contributions made in the field of radio astronomy.

Giant Metre wave Radio Telescope (GMRT)

• It is an array of 30 antennas positioned in a ‘Y’ fashion, centred at Khodad village in Junnar taluka of Pune district.
• Operated by the TIFR – National Centre for Radio Astrophysics (NCRA), the GMRT was the brainchild of late Govind Swarup.
• Extensively used for studying the universe in low frequency since 2000, the telescope has been instrumental in many path-breaking discoveries. Scientists from more than 40 countries are beneficiaries of data obtained from this telescope.

Institute of Electrical and Electronics Engineers (IEEE)

• The IEEE is the world’s largest technical body publishing research from the fields of engineering and computing, in addition to awarding standards to institutions and organisations involved in these fields.
• J C Bose’s demonstration of generation and reception of radio waves (1895) and the discovery of the Raman Effect by C V Raman (1928) have been the only IEEE milestone winners from India, till date.
• However, their discoveries were recognised as late as 2012.
• IEEE considers an institution for the milestone on the basis of engineering, science, and computational facilities it offers for not less than 25 years.
• It seeks well-documented history and consistent contributions provided by the institute.

Hence all statements are correct.
