To meet the observation requirements of atmospheric environmental, water environmental and ecosystems etc., China has planned a number of comprehensive environmental observation satellites, including the Gaofen-5 satellite, the hyperspectral observation satellite, the atmospheric environment monitoring satellite, the high-precision greenhouse gas monitoring satellite and the hyperspectral integrated observation satellites. The spectrum of the comprehensive environmental observation satellites covers from ultraviolet to longwave infrared, and the observation means of the satellites include multi-spectral, hyperspectral, polarization, multi-angle, active lidar etc. The satellites are characterized by hyperspectral, high quantitative, high accuracy and multi-detection methods, and becoming the symbol of China's hyperspectral remote sensing capability. In this paper, the development status of China's comprehensive environmental observation satellites is summarized. The detection capability is analyzed from two aspects: the integrated terrestrial observation capability and the integrated atmospheric observation capability. The comprehensive application examples and efficiency under the existing system is given. The shortcomings of the existing environmental observation system are analyzed from the aspect of observation timeliness, spatial resolution, detection elements, etc., and the development suggestions are given for the subsequent development of environmental comprehensive satellites.
