(i) Gauribidanur RAdioheliograPH (GRAPH)
GRAPH is a two-dimensional radio interferometric array dedicated to image the solar corona in the frequency range 40 – 150 MHz.

(ii) Gauribidanur Radio Interferometric Polarimeter (GRIP)
GRIP is a one-dimensional radio interferometer system built by IIA to observe the polarized radio flux from the whole Sun simultanesously at many frequencies in the frequency range 40 – 150 MHz.

(iii) Gauribidanur LOw frequency Solar Spectrograph (GLOSS)

(iv) Gauribidanur RAdio Spectro Polarimeter (GRASP)
GRASP antenna system is designed to observe the polarization properties of the non-thermal radio emission from the solar corona over the frequency range 50 – 500 MHz. It can produce both Stokes-I and Stokes-V spectra simultaneously.
