Everyone has probably looked at the night sky at least once and wondered about the creation of the universe. Astronomers continue to study the fundamental questions of the universe using science. Radio astronomy is the field of studying the phenomena of the universe by receiving radio waves from the universe through a radio telescope.

…
In 2015, Spanish and Australian radio astronomers proposed developing a miniaturized receiving system that could be easily installed on radio telescopes in each country. To this end, he stayed at the California Institute of Technology for a year and, after three years of joint research with JPL, developed the world’s first ultra-small, three-channel (22 GHz, 43 GHz, and 86 GHz) receiving system in 2018.

The Italian National Astrophysical Center was commissioned to create three micro three-channel reception systems for installation on three radio telescopes. It was awarded through international bidding in 2020, successfully developed, and exported in August 2022. Germany and Finland are also developing this reception system for installation on their own radio telescopes.

The optical circuit of the receiver we developed and provided is also installed in the radio telescope jointly owned by Japan and Spain, and is used for observations. The receiving system not only provides a new means of observation and research for the domestic and foreign radio astronomy community, but has also been adopted as an international observational standard and is widely used in each country. Now, Korea’s space radio receiver manufacturing technology is no longer on the periphery but at the center of the world’s radio astronomy community.

Thank you, everyone.
