Giant Metrewave Radio Telescope-Tata Institute of Fundamental Research
This visit was arranged on 14th October for Third year and final year (Electronics and Telecommunication) students from B.Tech. Total 39 students visited to GMRT with coordinator Ms.S.S.Deshpande (Asst. Prof. ETC) along with Mrs. S.P.Kodgire (Head Electronics and Telecommunication). This visit was part of their syllabus for subject Digital Communication and Information Theory.
NCRA, a center of the school of natural sciences of the TIFR, has set up a unique facility, the Giant Metrewave Radio Telescope for radio astronomical research at metre wavelengths. GMRT is a very versatile instrument for investigating a variety of radio astrophysical problems ranging from nearby Solar system to the edge of observable Universe.
NCRA runs both short and long term student technical training program. The short term programs are mainly during the summer and are meant for students in their pre-final year. The long term program runs during the academic year and are meant for final year students.
The SP programs are open to students in their pre-final/final year of - BE/BTech (Any Branch).
Projects are offered in a wide range of topics including Electronics (Analog/Digital) Instrumentation Signal Processing
Data Analysis and Image Processing
The GMRT contains 30 fully steerable telescopes. There are fourteen telescopes randomly arranged in the central square 1 km by 1 km in size, with a further sixteen arranged in three arms of a nearly "Y"-shaped array each having a length of 14 km from the array centre. The GMRT is an interferometer which uses a technique known as aperture synthesis to make images of radio sources. The GMRT operates in six frequency bands centered at 38, 153, 233, 327, 610, and 1420 MHz.
Each antenna is 45 meters in diameter with the reflector made of wire rope stretched between metal struts in a parabolic configuration. This configuration works because of the long wavelengths (21 cm and longer) at which the telescope operates. Each antenna has four different receivers mounted at the focus. Each individual receiver assembly can rotate so that the user can select the frequency at which to observe.
The maximum baseline in the array gives the telescope an angular resolution (the smallest angular scale that can be distinguished) of about 1 arc second at the frequency of neutral hydrogen (1420 MHz).
