Very Long Baseline Interferometric (VLBI) observations at the Hat Creek Radio Observatory (HCRO) and VLBI research within the Radio Astronomy Laboratory (RAL) of the University of California at Berkeley have been made since 1967. In 1975 the University of California formed a Consortium along with four other universities to coordinate VLBI activities of their Network of radio telescope facilities. Support is provided for the continuing participation of the HCRO 85-ft antenna during regular U.S. and Global Network VLBI observations, and for VLBI-related research on galactic and extragalactic topics. Support for the VLBI observations on the telescopes in the ad hoc VLBI network will be phased out as the Very Long Baseline Array becomes operational. THe technique of VLBI in radio astronomy allows the observations of the physical structure in radio sources at scales that cannot be obtained by any other methods.

自 1967 年以来，哈特溪射电天文台 (HCRO) 的甚长基线干涉 (VLBI) 观测和加州大学伯克利分校射电天文学实验室 (RAL) 的 VLBI 研究一直在进行。1975 年，加州大学与其他四所大学一起成立了一个联盟，以协调其射电望远镜设施网络的 VLBI 活动。 支持 HCRO 85 英尺天线继续参与美国和全球网络 VLBI 定期观测，以及银河系和河外主题的 VLBI 相关研究。 随着甚长基线阵列投入运行，特设 VLBI 网络中望远镜对 VLBI 观测的支持将逐步取消。 射电天文学中的 VLBI 技术允许以任何其他方法无法获得的尺度观测射电源的物理结构。
