The Small Radio Telescopes

We are in possession of two small radio telescopes (SRTs) with a diameter of 90″ (2.3m) each. This kind of telescope was developed at the MIT Haystack Observatory. Azimuthal and elevation drives allow to point the telescopes at any position on the sky. See the MIT wiki for detailed information.

These telescopes are used for educational purposes as part of our student lab course. Key topics are the measurement of the sun as thermal as well as the milky way as non-thermal source. We are in particular able to measure the rotation curve of the milky way to sufficiently high precision. The analysis of signals from geostationary satellites as well as other artificial emitters shall demonstrate the problems observers face with radio frequency interference (RFI). The measuring technique is reminiscent of the one used at larger modern facilities, which we use to retrieve scientific data for example for Active Galactic Nuclei.
