After that, BRIN will install primary and tertiary mirrors as well Obnas Timau the. Meanwhile, the main instrument in the form of a telescope with a diameter of 3.8 meters and a dome with a diameter of 14 meters have been built around 55%.
With this progress, BRIN targets the space monitoring facility to be completed in 2023.
