1. Fundamentals of Satellite Remote Sensing Technology

Abstract
The history of remote sensing satellites in China dates back to the 1970s. The remote sensing satellite has been developed from recoverable satellites to transmission satellites with different spectrum segments, such as visible light, infrared, hyperspectral, and microwave bands. During the development, key technologies such as high-resolution large-scale optical system, Synthetic Aperture Radar (SAR) payload, hyperspectral imaging, high-precision dynamic imaging, and high-orbit imaging have been conquered and a series of four major operational satellites for resources, meteorology, oceans, and environment disaster relief have been established. At present, China’s satellite remote sensing data have provided big data service support for industries, such as national land and mineral resources management and monitoring, traffic network safety monitoring, geological hazard early warning, air and water environmental pollution monitoring, agricultural and forestry growth, pest monitoring and yield assessment, flood and waterlogging disaster monitoring, hydraulic facilities safety monitoring, as well as Earthquake disaster monitoring. Satellites FY series, and HY series have become one of the international meteorological and ocean satellite data sources.

3. Analysis and Design of High-Resolution Visible Spectral Remote Sensing Satellite System

Abstract
As the earliest optical remote sensing satellite, visible spectral remote sensing satellite is of great and profound significance for satellite remote sensing system. High-resolution optical remote sensing satellites have a vast application prospect in mapping, construction, mining, urban planning, land use, resources, management, agricultural investigation, environmental monitoring, emergency relief and geographic information services, and also in military imaging reconnaissance.

4. Design and Analysis of Infrared Remote Sensing Satellite System

Abstract
Space infrared remote sensing technology is widely used in many fields such as land and resource, ocean, surveying and mapping, agriculture, forestry, water conservancy, environmental protection, meteorology, disaster reduction, earthquake, and national defense, especially in water pollution monitoring, urban infrared remote sensing, and national security and national defense applications. Space infrared remote sensing technology usually refers to the acquisition technology of thermal radiation information of the interested targets through infrared remote sensing instruments or sensors on a space platform (satellite, space station, etc.).

5. Design and Analysis of Hyperspectral Remote Sensing Satellite System

Abstract
Hyperspectral is generally defined as the spectral resolution that is higher than 1/100 of wavelength. Hyperspectral could be reserved for interferometer type imaging sensors with a very fine spectral resolution. The hyperspectral remote sensing system mainly in visible and infrared spectral bands can acquire the spatial size and distribution information of the target. In addition, it can accurately depict the “continuous” electromagnetic spectral reflection characteristics of ground objects in narrower and denser imaging bands. This imaging method, which simultaneously obtains spatial and spectral information of objects, is called “imaging spectroscopy.” Hyperspectral remote sensing system is one of the most effective space remote sensing systems for monitoring the dynamic changes of the Earth’s environment and quantitative retrieval by remote sensing. It is widely used in the fields of Earth science and applications, deep space exploration and security and defense.

Abstract
Since the space-borne Synthetic Aperture Radar (SAR) is not affected by weather and climate, and can perform large-area Earth observation around-clock, all-weather and with high resolution, it has become an important technical means for Earth observation and has been widely used in various fields of the national economy, such as ocean condition monitoring, geological surveys, agriculture, water conservancy, and disaster surveillance.

8. Design and Analysis of High-Precision Microwave Remote Sensing Satellite System

Abstract
Over 70% of the Earth’s surface is covered with oceans rich in renewable and nonrenewable energy, which plays an important role in regulating the global climate. The ocean microwave remote sensing satellite system has become an irreplaceable high-tech means to understand, research, develop, utilize, and manage the ocean by its advantages of all-time, all-weather, large area, multi-scale, synchronization, fast, high frequency, short-cycle, long-term continuous observation, etc., that is not limited by geographical location and human conditions, as well as the coverage ability of critical environmental and politically sensitive sea areas.

9. Design and Analysis of Optical Remote Sensing Satellite System on Geostationary Orbit

Abstract
Geostationary Orbit Optical Remote Sensing System (hereinafter referred to as “GEO Optical Remote Sensing System”) combines high spatial resolution and extremely high temporal resolution, which is an important direction for the development of ground remote sensing system. High-resolution optical remote sensing system in geosynchronous orbit can quickly acquire the information on interested objects through its real-time task response ability. Unlike previous GEO meteorological satellites or missile early warning satellites, the satellite with the high-resolution optical remote sensing system is generally with the spatial resolution of visible light load on geosynchronous orbit superior to hundreds of meters order of magnitude, and infrared load resolution superior to kilometers order of magnitude.
