Abstract: Based on the application of on-orbit capture in space missions,the evolution of on-orbit capture technology is presented in this paper.At present,autonomous and unmanned technique is an important development direction of on-orbit capture.Based on several typical autonomous on-orbit capture systems,the related key technologies and development status are presented,and the limitations of rigid on-orblt capture based on space manipulators are indicated.A new flexible on-orbit capture mode based on flexible net is proposed,which is more advantageous than rigid capture and is a new development trend for on-orbit capture.
