The S3 VLBI data record/playback system
Abstract
Future scientific applications of VLBI are being planned that will require significantly increased sensitivity in the VLBI systems. Such applications include space VLBI missions in which VLBI observations are to be carried out on rapidly rotating baselines with lengths exceeding 30,000 km. In order to provide the required sensitivity for continuum observations VLBI systems with data rates in the range 1024 Mbit/sec to 8192 Mbit/sec are required. The ``S3'' VLBI data record/playback system, under development in the Space Geodynamics Laboratory at CRESTech, based on an array of digital video tape transports, will provide user data rates of 1024 - 2048 Mbit/sec with an architecture suitable for upgrading to 4096 Mbit/sec and beyond as advances in tape transport technology permit.
