The Cambridge Low-Frequency Synthesis Telescope (CLFST) is an east-west aperture synthesis radio telescope currently operating at 151 MHz. A radio telescope is a form of directional Radio antenna used in Radio astronomy and in tracking and collecting data from Satellites The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. It consists of 60 tracking yagis on a 4. 6 km baseline, giving 776 simultaneous baselines. These provide a resolution of 70×70 cosec(declination) arcsec2, with a sensitivity of about 30 to 50 mJy/beam, and a field of view of about 9°×9°. The field of view (also field of vision) is the angular extent of the observable world that is seen at any given moment The telescope is situated at the Mullard Radio Astronomy Observatory. Mullard Radio Astronomy Observatory ( MRAO) is home to a number of large Aperture synthesis Radio telescopes including the One-Mile Telescope,
The CLFST has made three astronomical catalogues of the Northern Hemisphere:
