Discussion on Future Configuration Design of Chinese Astrometric and Geodetic VLBI Network

We discuss the future configuration of the Chinese astrometric and geodetic VLBI network.The technical specifications of equipments at observation stations and the corresponding necessarily required investment are proposed based on the history,current status and near future development of the domestic and international VLBI technology from the view point of astrometry,space geodesy and deep space exploration.This configuration is only for the criticism and reference in order to minimize the investment,maximize the efficiencies and the integration of various efforts and resources.
