Chinese Deep Space Network

The Chinese Deep Space Network is a network of large antennas and communication facilities that supports the lunar and interplanetary spacecraft missions of China. It is managed by the China Satellite Launch and Tracking Control General (CLTC).[1][2]
The network was first needed for the lunar mission Chang'e 1,[3][4] but will be used to support future missions to the moon and Mars. Similar networks are run by the USA, Russia, European countries, Japan, and India.
Network[edit]
As of 2007, the network consisted of:
- Ground control stations in Kashgar and Qingdao (in the Shandong province).
- 18 meter antennas in Qingdao and Kashgar
- A 50-meter antenna at Miyun (~116°E), near Beijing.
- A 40-meter antenna in Yunnan (~101°E).
Planned improvements by 2012, to support Chang'e 3 and Chang'e 4, include:[5]
- Upgrades to the ground facilities at Kashgar and Qingdao, and a deep-space ground control station at Jiamusi.
- A new 35-meter antenna at the Kashgar station.
- A 64-meter antenna in Jiamusi. (~130°E)
As of 2017, China was constructing an additional ground station in South America, in the Neuquen province of Argentina (~70°W), with a 50 million-dollar investment. The facility, a part of China's Lunar Exploration Program.[6][7] It was inaugurated in October 2017.[8] The station is seen by some as a symbol of China's increased role in South America's politics and economy.[9]
Uses[edit]
The network was used to track Chang'e 2, first to L2[10] and then to asteroid Toutatis.[11]
