Automated Remote Operation System and Data Analysis System for the Key Stone Project VLBI Network

Since one of the main objectives of the Key Stone Project VLBI Network is to measure position changes of four VLBI stations associated with large Earthquakes around Tokyo area, daily observations and fast data processing system are required. To achieve these requirements, highly automated remote operation system and data analysis system have to be developed. The remote operation system of the Key Stone Project can perform daily observations without operators at each VLBI station except for the tape change operation once everyday. The automated data analysis system is also able to analyze VLBI data automatically with occasional operator maintenances. In the earliest case, the analyzed results were produced within 24 hours from the last observation ends.
