Space HubGiant Metrewave Radio Telescope (GMRT)
Facility Overview & Institutional Scope
"GMRT is a major radio astronomy observatory operated by the National Centre for Radio Astrophysics (NCRA-TIFR). It consists of radio telescopes used to study distant galaxies, pulsars, quasars and other astronomical objects. It is one of the world's most powerful radio telescopes at low radio frequencies."
Operating under the Department of Space (DOS), Government of India, Giant Metrewave Radio Telescope (GMRT) serves as a vital node in India's sovereign space program. Located at Khodad, near Narayangaon, Pune, Maharashtra, the center houses advanced engineering labs, ground control telemetry terminals, and specialized payload test complexes that contribute directly to national space missions including Chandrayaan lunar probes, Gaganyaan human spaceflight, Aditya-L1 solar observatory, and the NavIC satellite navigation constellation.
History & Evolution of Giant Metrewave Radio Telescope (GMRT)
Established to strengthen India's self-reliant space capabilities, Giant Metrewave Radio Telescope (GMRT) has evolved from early sounding rocket support and experimental ground terminals into an internationally recognized hub for space science and aerospace engineering. Over the decades, engineers and scientists at Khodad, near Narayangaon, Pune have developed pioneering indigenous technology, reducing dependence on foreign satellite infrastructure and enabling cost-effective space exploration.
The facility plays an integral role in testing and validating hardware under extreme space environments, ensuring high reliability for multi-year satellite lifespans and deep-space trajectory maneuvers.
