The São Gião Radio Telescope is situated in the parish of São Gião Portugal. It was constructed in 2015, with first light in December 2015.[1] The gregorian telescope has a diameter of 9.3 m. As of 2019[update] it is the biggest radio telescope in mainland Portugal. Two 3 phase motors drive the azimuth and elevation (oraltitude) servo systems with an accuracy of 0.01 degree. The main reflector has a solid reflector surface that makes it suitable for observations of high frequencies up to 22 GHz.[2]
It is used to observe the hydrogen line from our galaxy and maser signals from star-forming regions and late evolution AGBorOH/IR stars.[3] The frequencies used for the hydrogen line is 1.42 GHz and maser signals are measured on 1.612,[4] and 12 GHz[5] The data results obtained with the telescope were presented on EUCARA 2016 Dwingeloo Netherlands [6] and on the ASTROFESTA 2018 in Constancia Portugal.[7][8] The telescope data and methods are also referenced by universities like the Western Kentucky University,[9] and societies like Ofiuco[10] and the Society of Amateur Radio Astronomers.[11]
