China To Construct Ground Stations in Antarctica

China planned new satellite-data-acquisition antennas at Zhongshan Station in Antarctica to support polar-orbiting spacecraft.

2 Feb 2023: China Space News reported that a CASIC subsidiary won a bid to build an ocean-observation satellite ground system at Zhongshan Station in Antarctica. The project adds ground-station facilities supporting satellite data acquisition. Video tour of Zhongshan Station.

– Renderings of the roughly 43.95 million yuan project showed four radome-covered antennas at Zhongshan in East Antarctica.

– The antennas would support data acquisition from Chinese satellites in polar and near-polar orbits, which pass near the poles multiple times each day and therefore offer frequent downlink opportunities.

– The spread of Chinese international ground stations has generated concern, particularly with infrastructure in South America. The issue notes that systems with clear civilian uses can also have dual-use value.

– Construction at Zhongshan, around 69° south latitude, could allow China to receive remote-sensing, weather, surveillance and other satellite data faster.

– Zhongshan Station is China’s second Antarctic research station, opened in Feb 1989, and can support roughly 60 summer and 25 winter personnel.

Ground stations are critical spacecraft infrastructure for receiving data and transmitting commands, making them another potential area of strategic competition among space powers.
