The development of the Korea-Japan Joint VLBI Correlator (KJJVC) has been completed and installed to correlate the observed data from KVN (Korean VLBI Network) of KASI (Korea Astronomy and Space Science Institute) and VERA (VLBI Exploration of Radio Astrometry) of NAOJ (National Astronomical Observatory of Japan) in October 2009. The MoA (Memorandum of Agreement) of joint operation for KJJVC had been exchanged between KASI and NAOJ with a close cooperation in July 2011. KJJVC is composed of the various playbacks, raw VLBI data buffer (RVDB) system, VLBI correlation subsystem (VCS), data archive (DA) system, and control and operational software. The VCS is designed for correlation processing maximum 16 stations, a maximum of 8 Gbps/station, and 8,192 output channels for VLBI observation data. The system configuration, the operational results, and future plan would be introduced in this paper. |
