Three loads of atmospheric environmental monitoring satellites passed the design review

[ Instrument Network Instrument Development ] From October 23 to 24, Anguang's atmospheric environment monitoring satellite high-precision polarization scanner (POSP), multi-angle polarization imager (DPC) and ultraviolet hyperspectral atmospheric composition detector ( EMI-II) passed the formal design review organized by the Shanghai Satellite Engineering Research Institute's Atmospheric Environmental Monitoring Satellite Project Office and was transferred to the prototype development and production stage.

The Atmospheric Environment Monitoring Satellite is a scientific research satellite in the national civil space infrastructure planning and an important part of China's atmospheric environment monitoring. Multi-angle Polarization Imager (DPC) provides multi-angle multi-spectral polarized radiation data, combined with atmospheric inversion models to provide global atmospheric aerosol and cloud properties; high-precision polarization scanners (POSP) for surface polarization decoupling, Improve the accuracy of atmospheric polarization detection, and provide data for the correction of the particle concentration of the entire atmosphere to the near-surface layer; DPC and POSP two types of polarization detection load can also achieve the target by matching the observation elements such as field of view, band and time. Centralized observation" (also known as "crossfire detection"), at the same time, high-precision acquisition of comprehensive information of atmospheric aerosol multi-spectral, multi-angle and polarized radiation, in order to achieve higher precision atmospheric aerosol comprehensive parameter inversion; UV hyperspectral atmosphere The Component Detector (EMI-II) enables quantitative monitoring of the distribution and variation of trace components in the global atmosphere.

At the positive design review meeting, the review experts reviewed the positive design report of the load, the reliability and safety design and analysis report, and the correct technical risk identification and evaluation analysis report. After discussion and inquiry, the review team believes that the technical status of the three load samples is clear, the technical process of development is reasonable and feasible, and the design results of various functions and performance indicators meet the requirements of the development work book; the reliability and safety design and analysis are carried out. Work, in line with the provisions of the eight-yard satellite model reliability, safety assurance general outline; carried out risk identification and analysis work, in line with the requirements of the Aerospace Science and Technology Group Corporation technical risk control implementation requirements; document data specifications, complete, in line with the "eight hospital satellite The requirements of the Model Design Review Implementation Requirements.
