A three-element Very Long Baseline Interferometry network consisting of three identical 21-m dishes in South Korea, owned and operated by the Korea Astronomy and Space Science Institute (KASI). It began operation in 2011. The dishes are at Seoul (the Yonsei Radio Telescope), Ulsan (the Ulsan Radio Telescope), and Jeju Island (the Tanma Radio Telescope), and are remotely controlled from KASI in Daejeon. The dishes work at wavelengths between 14 and 2.1 mm, and the longest baseline is 476 km (Yonsei to Tamna).
