Welcome to EAVN/APT web site


Very Long Baseline Interferometry consists of many radio telescopes which separate hundreds to thousands km. Such a long baseline yields the highest angular resolution than other any telescopes .

In East Asia, there are VLBI networks, Chinese VLBI Network (China), Japanese VLBI Network (Japan) and Korean VLBI Network (Korea). The East Asia VLBI Network (EAVN) consists of these VLBI networks. At the south of East Asia, there is another VLBI network, the LBA. The LBA consists of radio telescopes in Australia, New Zealand and South Africa. The EAVN can extend as the Asia Pacific antenna (APT) by collaboration with EAVN and LBA. The EAVN/APT collaboration started since 2004 and now a VLBI group in Taiwan join EAVN comminunity.
