Dr Srikanta Pal, an Indian scientist has rectified the problem of satellite signals interfering with the observation of the universe by the world's largest telescope in the US.
Dr Srikanta Pal solves the problem and said: “The Robert C Byrd Green Bank Telescope located at the National Radio Astronomy Observatory's site at Pocahontas County in West Virginia, US, had been exhibiting the problem ever since it was set up in August 2000”
Srikanta Pal, an associate professor in the Department of Electronics and Communication Engineering at the Birla Institute of Technology, Mesra, developed the electronics components needed to rectify the problem during his post-doctoral research in the University of Birmingham in the UK under the supervision of Prof Michael J Lancaster.
The scientist said that the Radio Astronomy Observatory had approached to his mentor Prof Lancaster to rectify the snag. Srikanta Pal, who hails from Bankura district in West Bengal, said he took up the challenge out of sheer interest.
The GBT is described as a 100-meter telescope, but the actual dimensions of the surface are 100 by 110 meters. The overall structure of the GBT is a wheel-and-track design that allows the telescope to view the entire sky above 5 degrees elevation. The track, 64 m (210 ft) in diameter, is level to within a few thousandths of an inch in order to provide precise pointing of the structure while bearing 7300 metric tons (16,000,000 pounds) of moving weight.
