Miyun Station of the National Astronomical Observatories

Miyun Station of the National Astronomical Observatories

Miyun Station of the National Astronomical Observatories is located on the northern shore of Miyun Reservoir in Miyun County, Beijing. Approved for construction in 1966, it served as one of China’s primary early bases for radio astronomy observations.

The station’s most significant piece of equipment is the Miyun 50-meter Antenna, which is the largest antenna system in China built specifically for the lunar exploration program and radio astronomy observations. The antenna stands 56 meters tall, weighs a total of 680 tons, and consists of three main components: the structure, the feed, and the servo control system.

Outside the compound, you can also see other observation equipment such as the meter-wave aperture synthesis array and a model of the 50-meter radio telescope.

Today, Miyun Station is almost no longer used for astronomical observations but is mainly dedicated to receiving data from the Chang’e lunar satellites.
