About

ERA is the Educational Radio Array radio telescope sited at the SPIRIT observatory south of Perth.

ERA is a 50 antenna radio telescope array built primarily for education and outreach purposes. The array is a fully functional radio interferometer and supports programs exploring: 

  • The electromagnetic (EM) spectrum 
  • the radio properties of the sun 
  • wave propagation and wave interference 
  • fundamentals of radio interferometry 
  • radio astronomy imaging and beamforming

For high school student projects, we will be doing most of our work in a sandboxed python environment called Jupyter Lab notebook.

The Jupyter Lab environment will need the notebook file below to be uploaded.

The data that ERA has collected for you need to be downloaded and unzipped into a folder.

We will be checking our data against the solar observatory in Learmonth, Western Australia.

The Telescope


ERA is a radio telescope array with 50 antennas arranged in a perturbed Reuleaux triangle configuration with diameter approximately 35m. The array uses commercial off-the-shelf (COTS) products for many of the components including antennas and receivers. The ERA antennas are optimised for 320-330 MHz, which includes the 325-327 MHz band that has some protections for radio astronomy. 

The antennas for ERA are 3-element Yagis fixed pointing at the zenith. The antennas, by design, see a large fraction of the visible sky (similar in concept to SKA-Low antennas), so ERA is sensitive to signals from a large fraction of the sky, and signals from specific radio sources can be isolated by radio astronomy imaging or beamforming.
