摘要：
Guidance, navigation and control of on orbit service spacecraft is the key to ensure mission success. According to its typical core task process, four key technologies have been identified, including the key technical problems such as the ultra-close stereo vision measurement of the rolling target, the planning and control of the attitude and orbit coupling approach path of the rolling target, the compliance capture of non-cooperative target, and the stability control of the combination. Methods such as precise perception of typical parts based on deep learning, optimization trajectory based on virtual domain inverse dynamics, indirect estimation assisted image visual servo control, and impedance control based on position control inner loop are proposed. The precise navigation, guidance and control of the combined spacecraft are realized. Ground tests are verified by using the air floating platform and six degrees of freedom motion simulator. The three-axis control accuracy of the combined spacecraft is 0.2 ◦. Finally, the future development of on orbit service spacecraft is prospected in order to play a reference role for the follow-up research in this direction. © 2023 Editorial Department of Journal of Chinese Inertial Technology.
