The '''Gauribidanur Radio Observatory''' is a radio telescope observatory located at [[Gauribidanur]], near Bengaluru. It is operated jointly by [[Raman Research Institute]] and the [[Indian Institute of Astrophysics]]. The observatory has been in operation since 1976.

==Location==
The Gauribidanur Observatory is located at Gauribidanur kolar diatrict (Latitude:13.60° N; Longitude:77.44° E), 100 km north of Bengaluru.

==Science and observation==
The Observatory has been used for studying various aspects of the Sun, galaxies and pulsars.

A few observations with the array have been the first two-dimensional images of radio emission from slowly varying discrete sources in the outer [[solar corona]], an all-sky survey of radio sources at 34.5 MHz in the declination range -30° S to 60° N, and a low frequency carbon recombination lines in astrophysical sources. Studies have also been done of gaseous remnants of exploding stars and the apparently vacant space between members of a cluster of galaxies. Currently, the studies are targeted at [[pulsars]].

==Facilities==
The Gauribidanur Observatory has a 6-meter [[radio telescope]], a radio [[heliograph]], a high resolution radio spectrograph and a gravitational laboratory.

===Gauribidanur Telescope===
The Gauribidanur Telescope is a decameter wave radio telescope. It consists of 1000 dipoles arranged in a "T" configuration. It consists of 1.4 km East-West Arm and a 0.5 km South Arm.<ref>{{cite web|title=Gauribidanur Telescope|url=http://www.iiap.res.in/centers/radio#geetee|website=The Indian Institute of Astrophysics|accessdate=25 August 2014}}</ref>

===Gauribidanur Radio Heliograph===
The Gauribidanur Radio Heliograph is a radioheliograph used to obtain two dimensional pictures of the outer solar corona at frequencies from 40-150 MHz. It has been operating since 1997. It consists of 192 log-periodic dipoles arranged in a "T" configuration.<ref>{{cite web|title=Gauribidanur Radio Heliograph|url=http://www.iiap.res.in/centers/radio#grh|website=The Indian Institute of Astrophysics - Gauribidanur Radio Heliograph|accessdate=25 August 2014}}</ref>
