The Decameterwave radio telescope at Gauribidanur: Antenna arrays and control system

Abstract

The Raman Research Institute and the Indian Institute of Asrtophysics in a joint cdlaboration program constructed a large decameter wave radio telescope at Gauribidanur, Karnataka, India (Latitude: 13'36' 12" and Longitude 77' 26' 07") which is in operation for several years now. This Decnmeter-wave Radio-Telescope, operating at 34.5 MHz, consists of 1,000 broad band dipoles arranged in the form of the letter "T". In this paper, we present technical details of the antenna arrays, the declination scanning system and the tracking system in hour angle.
