Abstract

An overview is presented of recent developments on very-long-baseline interferometry (VLBI) at the Shanghai Observatory. The Shanghai Radio Station, which is equipped with a 25-m antenna, and other facilities that became operational in 1988, are described. The VLBI data-processing system is discussed. It includes an S-2 VLBI data processor and a series of postcorrelation processing programs for astronomy as well as geodesy. There are now two VLBI groups in Shanghai Observatory working on astronomy and geodynamics, and some current research is outlined
