Abstract:China Remote Sensing Satellite Ground Station (RSGS), affiliated to the Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences (CAS), is one of the large national research infrastructures. After more than two decades of development, RSGS has formed its integrated satellite data reception, transmission, archiving, processing and distribution systems, i.e., an operation pattern with Beijing headquarters as the operation management and data processing center, and Miyun, Kashi, and Sanya Stations as the data reception network. In RSGS, the data reception, transmission, processing, management and distribution system operate collaboratively, making it one of the core infrastructures in the field of earth observation in China. The Kashi and Sanya Stations were built and put into operation in 2008 and 2010, respectively, along with the former established Miyun Station, the satellite ground receiving station network covering the whole territory of China has basically taken shape. Presently, the data reception mask of RSGS can cover the whole territory of China and 70% of Asian territory. In addition, a high-speed data transmission optical fiber network has been built between the three reception stations and the headquarters. The data reception system of RSGS consists of the antenna, feed and servo subsystem, the tracking and receiving subsystem, the testing subsystem, the data recording and quicklook subsystem, the error diagnosis subsystem, the station monitoring management subsystem, and the technical support subsystem, whose capabilities and performances are in the front rank of similar ground stations in the world. Since operation, it has received data from 14 foreign earth observation satellites such as LANDSAT, SPOT, and RADARSAT, as well as 10 domestic earth observation satellites such as CEBERS, HJ, and ZY-03. RSGS has a group of international advanced satellite data processing and production systems, and the quality and specifications of their products are consistent with the data products worldwide. In addition, with the completion of a number of major equipment innovation projects, the capacity of the satellite data receiving, processing, storage, and retrieval systems has been significantly improved, and it guarantees to provide data products to users at the near real-time speed. In more than 2 decades since its operation, the date received, processed, and distributed by RSGS have been widely used in various remote sensing application fields, in which the most striking examples include the monitoring and assessment of major disasters, the implementation of the ground observation data sharing plan, the western region mapping for ecological environment quality assessment, the real-time marine monitoring and other data services to meet the major national remote sensing demands. The 12th and the 13th Five-Year Plan period is a prime period for high-speed development of earth observation in China. RSGS will continue to play its role as the core infrastructure in the earth observation field in China and constantly enhance the capacity of its satellite ground systems to make great contributions to the national economic and social development.
