Abstract:It is necessary to implement on-orbit capture before carrying out the on-orbit service and track clearance of space non-cooperative targets, and before on-orbit capture the non-cooperative targets generally need to be de-tumbling. This paper systematically investigates the de-tumbling methods for space non-cooperative targets at home and abroad, and classifies them based on energy transfer and energy loss. On the basis of summarizing the theory, operation process and key technologies of the two kinds of methods, the characteristics of each classification and its applicable scenarios are summarized. And then, the development of the future space non-cooperative targets de-tumbling methods is analyzed.
