SPIDER 300A installed in Medicina radio telescopes Visitor Center
“Marcello Ceccarelli” Medicina radio telescopes Visitor Center now has a new radio telescope, the SPIDER 300A! Installed close to the Northern Cross and the 32 meter single dish antenna professional radio telescopes, SPIDER 300A is used by researchers and students as an educational radio telescope and to let visitors discover radio astronomy and the tools they use to investigate the radio universe. SPIDER 300A is remotely controlled from the Visitor Center, where we installed the H142-One receiver for wave capture at a frequency of 1420 MHz and a computer with the RadioUniversePRO control software.
SPIDER 300A has been designed to be easily shipped and installed on a concrete base, on which C106-HEAVY column with high load capacity is fixed first of all and then the WP-100 waterproof computerized altazimuth mount head is installed on. Once the mount has been completed, the 3 meter diameter antenna is installed, which is equipped with a special support cell that keeps the structure rigid without putting too much effort on the antenna body.
After installing the antenna, the feed is connected with the two LNAs and all the connection cables, inserted in a special channel that connects the external radio telescope to the internal room of the Medicina radio telescopes Visitor Center. Here the H142-One receiver, the power supply and the control computer with the RadioUniversePRO software have been installed. In this way users can remotely control the SPIDER 300A radio telescope from the Medicina radio telescopes Visitor Center, point many radio sources and record many results such as radio maps, transits and spectra.
