Come 2018, upgraded GMRT will open new windows on the universe
In addition to being popular tourist spots in Maharashtra and Shivneri Lenyadri are the two main equipment of the control room of the giant radio telescope Metrewave (GMRT) and soon will follow a new era in exploration of the universe, the observatory to enter its last phase of its Upgrade to a next-generation installation.
Once the upgrade is completed, this observatory, now the largest astronomical telescope in the world operating on low frequency radio, has improved capabilities that will remain unparalleled until the Square Kilometer Array (SKA) The largest radiogram ever offered around the world, comes in about 2023.
“About 75-80% of the rise in electronics and existing systems of GMRTs was completed. Some of the new systems have already been commissioned to investigate and the first scientific results began to pass.” Yashwant said Gupta, dean of the observatory GMRT.
GMRTs is a range of 30 antennas extending over an area of 30 km in diameter, centered near the village of Khodad to Junnar Taluka, about 80 km from Pune. While 13 of these antennas are located in the central square of the observatory, a region stretching over 1 km by 1 km, the other arm are divided in 3 to about 14 km long in the direction East, West and South on “Y-shaped formation”.
It is used by astronomers around the world and is currently more than double the demand for its use as the time available for the slots.
The current GMRTs, conceived and designed in the late 1980s and built in the 1990s, respond to key scientific requirements and technical capabilities that time, allows astronomers to use in five limited frequency bands: 150 MHz, 234 MHz, 325 MHz, 610 MHz and 1000-1400 MHz, with a maximum bandwidth of 32 MHz.
However, with the update now, engineers and scientists have crossed a great leap in this frequency range, which will provide continuous coverage from 120 MHz to 1460 MHz with a near gap almost, and the maximum bandwidth 400 MHz, say Scientists, is more than 10 times greater than that of the original GMRTs system.
In other words, two major improvements in GMRTs mean that here it would be possible to receive radio signals from distant celestial objects with a wider range of distances in the universe; Second, it would detect weaker and newer objects, providing a deeper spectrum study for the astronomical community.
With an increase in input signal traffic due to improved electronics, scientists also identified the need to expand the capacity of transport, storage and calculating the observatory. The thing to note is that even if one performing refresher works, scientists do not waste time, but juggling schedules between old and new systems simultaneously to provide the maximum benefits to the user.
