The Giant Metrewave Radio Telescope (GMRT) based at Khodad, near Narayangaon in Pune district, which is hailed as the world's largest radio telescope facility operating at low frequencies, will once again be a leading instrument in the world helping astronomers to do cut-edge frontline research, with major upgrade work undertaken on the verge of completion.

Used by astronomers in numerous areas of astronomy and astrophysics, the inauguration of phase I of the upgraded GMRT will take place on Sunday in presence nuclear scientist Anil Kakodkar.

"Currently, all the systems of GMRT are going through an upgrade using latest analog and digital technologies and servo systems among other technologies to enhance the telescope performance and features, along with matching improvement in infrastructures such as civil, electrical and mechanical," a release issued by the National Centre for Radio Astrophysics (NCRA) said on Friday.

These improvements would increase the sensitivity of the GMRT by more than a factor of three and keep it on the forefront of the international scenario in the field for many more years to come, added the release.

GMRT consists of 30 fully steerable gigantic parabolic dishes of 45 meter diameter each, spread over 25 km area.

In operation since 2002, the telescope is considered as the most challenging experimental programme in basic sciences undertaken by Indian scientists and engineers.

Among other revamps, GMRT is also going to have new backend system to enable use of high bandwidth.

"Such a new backend system is being developed by NCRA engineers and scientists in collaboration with nVidia-India, the US-based Casper group, and Swinburne University of Australia," said the release.
