基于磁盘技术的1Gbps Mark 5 VLBI数据系统是麻省理工学院Haystack天文台正在开发的下一代VLBI。Mark 5系统主要使用低成本的基于PC的组件,支持高达1024 Mbps的数据速率记录到廉价的可移动IDE/ATA磁盘阵列。Mark 5型原型机组目前在多个电站和制冷机中使用,截至2003年初,约有25台机组在运行。Mark 5A装置现已从商业来源购买。
The 1 Gbps Mark 5 VLBI data system, based on magnetic-disk technology, is being developed at MIT Haystack Observatory as the next -generation VLBI. Incorporating primarily low-cost PC-based components, the Mark 5 system supports data rates up to 1024 Mbps recording to an array of inexpensive removable IDE/ATA disks. Prototype Mark 5 units are now in routine use at several stations and correlators, with ~25 units operating as of early 2003. Mark 5A units are now available from a commercial source.
