Environmental Disaster Reduction No. 2 Satellite Atmospheric Correction System Sub-system passed the appraisal and acceptance

[ Instrument Network Instrument Development ] On April 19th, the Environmental Disaster Reduction No. 2 Satellite Atmospheric Correction System Sub-system developed by Anhui Opto-mechanical Institute passed the appraisal and acceptance evaluation of the identification products organized by Aerospace Oriental Red Satellite Co., Ltd. in Hefei, Anhui.

The Environmental Disaster Reduction Satellite 2 is an important component of the resolution optical observation constellation in the National Civil Space Infrastructure Remote Sensing Satellite System. It consists of two satellites with identical technical states. Each satellite is equipped with an atmospheric calibration instrument. The atmospheric calibration instrument undertaken by Anhui Opto-mechanical Co., Ltd. detects the atmospheric multi-spectral information of the same field of view with the 16-meter camera of the satellite main load through the through-track scanning detection, and acquires the spectrum and polarization through time synchronization and spatial coverage detection. Information to achieve high-precision detection and inversion of aerosols and water vapor, and to obtain atmospheric parameters over the imaging area. With this atmospheric parameter as input, the ground-atmospheric correction model based on radiation transmission is used to correct the load image of a 16-meter camera, and obtain a clearer surface image to meet the application requirements of atmospheric correction of image data products such as 16-meter cameras.

From March 27 to 28, Dongfanghong Company conducted an acceptance test on the atmospheric calibration instrument sub-system identification products in Hefei, and tested the mechanical interface, electrical interface, function and performance of the product. The test results met the atmospheric calibration instrument identification product technology. Requirements. From April 18 to 19, the expert group reviewed the identification of the product data package, listened to the development and quality summary of the atmospheric calibration instrument identification product and the product assurance summary, and concluded that the atmospheric calibration instrument sub-system identification product completed the various provisions of the development technical process. Work, function, performance and interface meet the requirements, according to the Fifth Institute Dean's Order (No. 5, No. 01), model production and maintenance requirements, production and maintenance program and production and insurance work plan, carried out and completed product assurance and other related work, The product data package is complete and complete, and it is agreed to pass the appraisal product delivery acceptance review.

Dongfanghong Company has placed great hopes on the development team of Anguang Institute of Atmospheric Calibration. The review experts pointed out that the innovation of the Environmental Disaster Reduction No. 2 satellite is mainly in the development of the atmospheric calibration instrument. It is hoped that the development team will fully complete the established indicators of the atmospheric calibration instrument to achieve the satellite's established atmospheric correction function. The development team of Anguang said at the appraisal and acceptance review meeting that it must do its utmost to complete the development task of the satellite load atmospheric calibration instrument.
