China Remote Sensing Satellite Ground Station

China Remote Sensing Satellite Ground Station (RSGS) was established and put into operation in 1986, with its Chinese name inscribed by Mr. Deng Xiaoping.

RSGS is not only a major national science and technology infrastructure but also a member of international ground stations group on Earth Observation. As one of the world's busiest ground stations, RSGS has received, processed and archived more than 50 satellites, 3.7 million scenes of satellite imagery since 1986.


With five ground stations built in Miyun, Kashi, Sanya, Kunming and the North Pole (Kiruna, Sweden), RSGS's data reception mask covers the entire Chinese territory and 70% of the land area of Asia. Global satellite remote sensing data can also be accessed efficiently.

The Miyun Ground Station started operating in 1986. The station is equipped with 6 sets of 12-meter antenna systems, one set of 11-meter antenna system and two sets of 7.3-meter antenna systems, as well as the corresponding data receiving, recording and transmitting facilities. The reception mask of Miyun Ground Station covers central China, northeast China and the neighbouring countries.

The Kashi Ground Station came into operation in 2008. It now has six sets of 12-meter antenna systems and two sets of 7.3-meter antenna systems. Its reception mask covers western China and central Asian countries.

The Sanya Ground Station was put into use in 2010. It is equipped with five sets of 12-meter antenna systems. Its reception mask covers the South China Sea and neighbouring countries in southeast Asia.

The Kunming Ground Station was put into operation in 2016. It has one set of 7.3-meter antenna system. Its range covers southwest China and the neighbor regions.

Kunming Ground Station


The North Polar Ground Station is located in Kiruna, Sweden. It was put into operation in 2016. Now it has one set of 12-meter S/X/Ka-band antenna system, which realizes remote control and automation operation. The North Polar Ground Station can improve China's capability of acquiring global remote sensing data.

After 30 years of development, RSGS has formed an integrated satellite data receiving, transmitting, archiving, processing and distributing system with Beijing Headquarters as the operation management and data processing centre, and the Miyun, Kashi, Sanya, Kunming and North Polar ground stations as the data receiving network. RSGS has become one of China's core infrastructure facilities in the field of earth observation.

In 1986, RSGS began to receive and process data from LANDSAT-5. In 1993, it started to receive and process SAR (synthetic aperture radar) data from the ERS-1 satellite of ESA and the JERS-1 satellite of Japan, realizing all-weather earth observation. In 1997 and 2008 respectively, RSGS succeeded in receiving and processing data from the RADARSAT-1 and RADARSAT-2 satellites of Canada, with multimode and full polarization SAR capacity. From 1998, RSGS has received and processed data from the French SPOT series satellites (including SPOT-1?SPOT-2?SPOT-4?SPOT-5?SPOT-6 and SPOT-7), providing high spatial resolution data to Chinese users. In 2015, RSGS started to receive and process French PLEIADES-1A and PLEIADES-1B satellites data, the spatial resolution of which is up to 0.5 meter.


Since 1999, RSGS has been responsible for receiving data from all China's earth observation satellites such as CBERS-01, CBERS-02, CBERS-02B, CBERS-04, CBERS-04A , HJ-1A, HJ-1B, HJ-1C, ZY-02C, ZY-1E, ZY-03, ZY3-02, SJ-9A, SJ-9B, GF-1, GF-1B/1C/1D, GF-2, GF-3, GF-4, GF-5, GF-6, GF-7,CSES and GFDM01.


Following the initiation of "CAS Strategic Priority Program on Space Science" in 2011, RSGS assumes the responsibility of tracking the near-earth satellites as well as receiving, recording and transmitting their data. The data service of RSGS has hence been extended from earth observation to space science. Since 2015, RSGS has succeeded in receiving data from China's Dark Matter Particle Detection satellite (DAMPE, "WuKong", SJ-10 satellite, Quantum Science Experimental satellite (QUESS, "MoZi", Hard X-ray Modulation Telescope satellite (HXMT, "HuiYan" and Microgravity Technology Experimental Satellite (KX-09, "Taiji-1".
