[1] The observatory was built in 1979 by the Institute for Astronomy[2] at ETH Zurich under the guidance of Prof. Dr. Arnold O. Benz.

Since that time it consists of two parabolic antennae of 7 m and 5 m diameter separated by 100 m and a lab building containing the spectrometers and other electronics.

Starting in 2014, the observatory is being converted to observe preferentially non-solar radiation of extragalactic and cosmological origin.

The most significant contribution was the survey and classification at decimeter wavelength (ultra high frequency).

The solar data since 1979, and the instrument descriptions are stored at the Institute of 4D Technologies[7] at Fachhochschule Nordwestschweiz FHNW in Windisch and are public.
