RSGS extend its facility Beginning last year, China Remote Sensing Satellite Ground St

ation (RSGS) started to extend its receiving range to cover the whole Chinese territory Establish western receiving station – Kashi, Xinjiang Uygur Autonomou

s Region of China

Establish southern receiving station – Sanya, Hainan Province of China

Expand receiving antenna at Miyun station – Beijing of China

The goal is to receive more than 15 satellites simultaneously Continuously as national receiving station to responsible for receiving ci

vil remote sensing satellites worldwide

Responsible to receive national resources satellite data such as the series of China-Brazil Earth Resources Satellites (Cbers’s), the Chinese constellation of small satellites for environment and disaster monitoring and forecasting (HJ’s)
