Shanghai Astronomical Observatory (SHAO), is an astronomical observatory in Shanghai. It has a long history of astrometry and also operates the 25m (82feet) Sheshan radio telescope as part of the Chinese VLBI array and the European VLBI Network (EVN).
It was formed in 1962 from the merger of the Xujiahui (also romanized as "Ziikawei") and Sheshan (Zose) observatories in Shanghai. It was involved with the Chang'e 1 Moon mission as the VLBI array is used for position determinations.
In October 2012 the Tian Ma 65m (213feet) radio telescope was completed for SHAO.[1] It is part of the Chinese Academy of Sciences.
