Abstract:

Since the start of an earth observation satellite remote sensing project four decades ago, the construction of satellite remote sensing systems in China has achieved tremendous development, forming three satellite remote sensing systems to enable the observation of land, ocean and meteorology. The construction of China High-resolution Earth Observation System (CHEOS) enables the development of many high-resolution satellite remote sensing technologies to international top levels and the cultivation of numerous research talents in this field. Key technologies such as the quality control of high-resolution remote sensing imaging, agile imaging in a maneuver mode and high-precision positioning provide important support for the economic construction, national defense and scientific research in China. This paper summarized the development, application and experience concerning the high-resolution Earth observation satellite remote sensing in China and compared its development status between China and other countries. Further, the paper proposed the development trend of high-resolution remote sensing systems in China to meet future development needs in the aspects of economy, environment, territorial resources and national security. Specifically, there is the necessity of speeding up the networking of Geosynchronous Orbit (GEO), Medium Earth Orbit (MEO) and Low Earth Orbit (LEO) high-resolution remote sensing satellites to improve application efficiency, making efforts to develop new remote sensing technologies including high-precision integrated optics and high-resolution Synthetic Aperture Radar (SAR) and building intelligent remote sensing application systems based on the collaboration of Internet, satellite remote sensing, big data, and digital Earth.
