Abstract

The Chinese Very Long Baseline Interferometry (VLBI) network (CVN) is a synthetic aperture radio telescope with the equivalent diameter up to 3000 Km. Through the electronic VLBI (e-VLBI) technology, the four stations and the data processing center are connected by the high speed network. e-CVN is a multi-purpose e-science platform with the merit of quick response ability. e-CVN has been successfully used in the near-real time critical lunar probe tracking missions. Besides, results of the preliminary e-CVN experimental investigations with the aim of rapid radio source mapping and rapid UT1 measurement are presented.
