摘要：Korea’s new VLBI project to construct the Korean VLBI Network (KVN) began in 2001 as a 7- year project that is fully funded by Korean government. We plan to build three new high-precision radio telescopes of 21-m diameter at three sites in Korea. We will install the 2/8, 22 and 43-GHz HEMT receivers by 2008, and later we will expand the receiving frequency range up to 129 GHz for astronomical, geodetic, and space research. As for the front-end system, we are going to install multi-channel receivers with low-pass filters within a quasi-optical beam transportation plate. With this system, multi-frequency phase referencing for millimetre-wave VLBI as well as simultaneous multi-frequency observations will be carried out. Mark 5B will be used as the recording system. We have completed the design of the KVN data acquisition system of 2 Gsps sampling rate, which will use 4 data streams to meet the multi-channel requirement.
