The Communications Research Laboratory (CRL), the National Astronomical Observatory (NAO), the Institute of Space and Astronautical Science (ISAS), and the Telecommunication Network Laboratory Group of Nippon Telegraph and Telephone Corporation (NTT) have developed a very long baseline connected interferometry 6-station array with a maximum baseline length of 208km, using a high-speed asynchronous transfer mode (ATM) network with an AAL1 that corresponds to the constant bit-rate protocol. The VLBI observed data (256 Mbps/station) is transmitted through a 2.488-Gbps [STM-16/OC-48] ATM network instead of being recorded onto magnetic tape. By combining antennas via a high-speed ATM network, a highly-sensitive connected interferometry system has been realized. The system was composed of two real-time VLBI networks: the Key-Stone Project (KSP) network of CRL (which is used for measuring crustal deformation in the Tokyo metropolitan area), and the OLIVE (Optically LInked VLBI Experiment) network of NAO and ISAS which is used for astronomy (space VLBI). These networks operated in cooperation with NTT. In order to realize connected interferometry, the acquired VLBI data (256 Mbps/station) were corrected via the ATM networks and were synthesized using the VLBI technique. The cross-correlation processing and data observation were done simultaneously.
