The Krean VLBI Network consists of 3 stations which have same performance, that is the KVN is a VLBI array. The antenna of KVN has very unique receiver system which can observe four different frequencies simultaneously. In near future, because the KVN will equip millimeter wavelength receivers, the KVN will play a very important role of the mm-VLBI experiment and science. The KVN also developed a new and best correlator whose name is Korea-Japan Joint VLBI Correlator (KJJVC). This correlator will be main correlator of the East Asia VLBI Network.
Although the baseline length of KVN is short less than 500 km, their receiver system is quite unique. The KVN receiver system has four different frequencies (22, 43, 86, 129 GHz) and these frequencies can be observed simultaneously. Any VLBI telescopes in the world do not have such a unique system. Moreover because a recent interests of VLBI development/experiment/science is mm-VLBI, the KVN will lead the mm-VLBI studies in the world. Moreover, the short baseline VLBI can detect object with extended structure, therefore the KVN provides us new sciences.
Because the KVN has a unique receiver system, the KVN will also provide us a new VLBI science. For example, a new and detailed nature of AGNs will be revealed by four frequencies and astronomical maser at higher frequency (86 GHz) will tell us a dynamics of gas around evolved stars.
The KVN and Japanese astronomers also developed a new and powerful correlator which is called KJJVC (Korea-Japan Joint VLBI Correlator). The KJJVC will be main correlator of the EAVN.
