Observations of 6.7 GHz methanol masers with East-Asian VLBI Network. I. VLBI images of the first epoch of observations

, 2014
Very-long-baseline interferometry (VLBI) monitoring of the 6.7 GHz methanol maser allows us to measure the internal proper motion of maser spots and therefore study the gas motion around high-mass young stellar objects.

Software Design for Kunming VLBI Station

, 2007
经过大量研究与论证，利用VLBI测量技术完成我国绕月卫星的精密测角（测轨）是完全可行的。为达到预定目标，上海天文台负责对昆明VLBI观测站进行软硬件改造，连同上海、北京、乌鲁木齐站，组成我国自有的VLBI网，共同完成对绕月卫星的测轨、定位及数据接收任务。 S3数据采集系统是昆明VLBI观测站的重要组成部分，对其终端系统的自动化控制是正确、迅速地监控、记录、实时传送相关数据的保证，进而确保整个昆明站能顺利完成VLBI测轨分系统安排的任务。2005年之前，在DOS操作系统环境下编写的非标准软件控制终端 ...

VLBI monitoring of the structure of the ICRF sources - The Bordeaux VLBI Image Database

The extragalactic radio sources that make up the International Celestial Reference Frame (ICRF) can exhibit extended and time-variable brightness distributions (or structures) on VLBI scales, setting limits on the accuracy of the astrometric source positions determined from the VLBI measurements. For this reason, regular VLBI observations are organized
