This proceedings has four thematic parts: advanced aerospace manufacturing technology, near space system and application technology, accurate perception technology of the earth, and collaborative fusion application technology. The CHREOCs (China High-resolution Earth Observation Conference) focus on the popular topics including military-civilian integration, the One Belt and One Road project, the transformation of scientific research achievements, and it also discusses the new ideas, new technologies, new methods, and new developments. The CHREOCs have effectively promoted high-level institutional mechanisms, technological innovation, and industrial upgrading in the high-resolution earth observation area, and arouse the influence of the national-sponsored major project.

All papers in this proceeding are from the 8th CHREOC, and most authors are the researchers and experts participating the state major project CHEOS. The papers are the extraction of research results and reflect the technique level and research direction of the field high-resolution earth observation. All articles have gone through the scientific and strict reviews for several rounds by the experts from the related fields, and therefore reflect the research level and technology innovation of the high-resolution field earth observation. It will be an informative and valuable reference for both academic research and engineering practice.

The year 2022 is the final year of high-resolution special projects. After more than ten years of construction, the task of high-resolution special projects has been basically completed, the core technology has been comprehensively breakthrough, and the typical achievements have been rapidly transformed, providing strong support for national security, national defense construction and national economic development.

Presided over the development of China's first sea defence missile solid engine, which was successfully used in anti-ship missile and achieved a significant technological leap. He served as the leader of the "five-star working group" of the aerospace ministry (1990), and achieved the first successful launch of five satellites in one year. He served as the deputy general commander of China's manned space program (1999-2002), led and organized the development and test of test ships and launch vehicles, and completed the launch and recovery of shenzhou I and ii. Weapons and equipment to develop the first as a group company at the same time, realize the continuous key defense weapon equipment first flight and test success, completed the new model and important stage of setting up a development task, realizes the five new satellite first launch successfully.Led and organized the establishment and implementation of several major space projects, actively promoted the management and innovation of space engineering, and made significant contributions to the sustainable development of China's space industry.
