  • The array consists of 36 identical parabolic Antennas.
  • The antennas work together as a single astronomical Inferometer.
  • Every antenna is equipped with a phased array feed.
  • A phased array feed creates beam of radio waves that can be electronically guided to points in different direction without moving the Antennas.
  • This increases the field of view of the telescope.

What is an Astronomical Inferometer?

  • It is an array of separate telescopes that work together as a single telescope to provide higher resolution of images of astronomical objects such as nebulous, stars and galaxies.
