摘要
1986年6月,上海天文台首次与日本和美国的三个VLBI台站联合组成了洲际VLBI干涉网并取得了干涉实验的成功,第一次精确测定了上海台6米天线与北美大陆的GilcreekK站之间的基线长度,并由5条基线综合分析的结果精确算出上海台与夏威夷的Kauai站之间的距离,同时进一步提高了上海台6米天线在全球VLBI坐标系中位置的精度。本文介绍了实验的基本情况,着重进行了实验数据结果的分析.
The first Japan-US-China joint VLBI experiment was carried out in June 1986. The main purpose of the experiment was to monitor the plate movement among the North American Plate, the Pocific Plate and the Eurasian Plate. Four Observation stations located in Shanghai (China), Kashima (Japan), Gilcreek and Kauai (USA) were connected as a VLBI network containing five baselines on which good fringes were obtained from 24-hour observations. We determined the baseline length between every two stations within errors of 2-5 cm and other baseline parameters precisely.
