Development of a radio telescope for the observation of celestial bodies in the Ku Band

Abstract

Abstract Solar events such as flares or explosions present intense radiation in the KU band (10-12) GHz, the range in which satellite television operates. Subsequently, the development of radio telescopes that make use of elements present in satellite television due to its low cost is evident around the world. The radio telescope in the study is, composed of a reflective mesh antenna, a mount that allows for remote operation, a Low Noise Block, and a satellite search engine. The system is installed in the Astronomical Observatory of the Technological University of Pereira and has a freedom of movement of 360° in azimuth and 180° in altitude, with a resolution of 0.2°. The set-up of the radio telescope was done by observing television satellites and registering the Solar transit. The developed radio telescope is easily scalable thanks to its modular architecture. Additionally, it is stable in adverse weather conditions because of its mesh antenna.
