Zhongwei Remote Sensing Satellite Calibration Field

"Promoting the construction of Ningxia Zhongwei Remote Sensing Satellite Calibration and Authenticity Inspection Field will help strengthen the country's space infrastructure and promote the development and upgrading of the calibration field to automation, integration, and sharing." - Jiang Xingwei

According to China Natural Resources News, Jiang Xingwei, a member of the National Committee of the Chinese People's Political Consultative Conference, academician of the Chinese Academy of Engineering, and former director of the National Satellite Ocean Application Center of the Ministry of Natural Resources, said that promoting the construction of Ningxia Zhongwei Remote Sensing Satellite Calibration and Authenticity Inspection Field will help strengthen the country's space infrastructure and promote the development and upgrading of the calibration field to automation, integration, and sharing; constructing the development system of high-resolution satellites from geometric remote sensing to quantitative remote sensing can effectively improve the geometric and quantitative remote sensing monitoring capabilities of high-resolution satellites, improve accuracy, be helpful to comprehensively and accurately understand the current situation and dynamic changes of carbon sources and carbon sinks, help government departments grasp the dynamics of carbon sources and sinks, realize development decision-making and process control, and promote the country to achieve the "double carbon" goal.

He suggested that additional funds should be invested to purchase and upgrade the existing equipment at the Ningxia Zhongwei Remote Sensing Satellite Calibration and Authenticity Inspection Field to better meet the calibration needs of the country's high-resolution special satellites and civil space infrastructure satellites. We should incorporate the Ningxia Zhongwei remote sensing satellite calibration and authenticity inspection field into the national remote sensing satellite calibration backbone field network, form the planning and implementation plan for the establishment of the remote sensing satellite national calibration center, accelerate the establishment of the national calibration center, and promote the connection between China's quantitative remote sensing technology level and the international level, and continuously improve the quality of the country's remote sensing image products. We should also increase policy support and promote the implementation of supporting industries. It is recommended to formulate relevant policies to support the construction and operation of commercial aerospace calibration fields, meet the normal calibration of domestic commercial satellites, improve the quality of commercial satellite products, and promote the development of the country's commercial aerospace.

Zhongwei Remote Sensing Satellite Calibration Field

Zhongwei Remote Sensing Satellite Calibration Field is under the guidance of the medium and long-term development plan of the national civil space infrastructure in the rapid development of global space remote sensing, jointly constructed by the Zhongwei Municipal People's Government, Wuhan University and Emposat Co., Ltd. This multifunctional integrated space application support platform is the world's first comprehensive calibration field integrating image remote sensing satellites and non-imaging altimetry satellites.

Zhongwei Remote Sensing Satellite Calibration Field has the characteristics of "one field for multiple purposes", adopts unattended automatic working mode, and is equipped with reflective moving point light source target, spaceborne synthetic aperture radar active calibration device, automatic angle reflector and spaceborne laser geometric calibration device, covering the calibration and authenticity inspection requirements of optics, synthetic aperture radar and laser satellite. It has the characteristics of low cost, high reliability, and multi-intelligence, and realizes a complete calibration system that reasonably matches many types of typical natural scenes and standard artificial targets in the test field. It also realizes the sky integrated graded authenticity inspection technology system with aviation flight test as the core, which can effectively support the strict aviation calibration flight of various loads such as visible light, near-infrared, infrared, laser radar, and synthetic aperture radar, and can support satellite in-orbit high-frequency radiation/geometric calibration, payload performance evaluation, and product authenticity inspection.
