For the Inertial Navigation System (INS) in hypersonic flight, when the centroid of the Inertial Measurement Unit (IMU) does not coincide with that of hypersonic vehicle, a lever-arm effect error will be generated, which will further expand in the dy

For a space manipulator with multiple links, joints, and degrees of freedom, it is necessary to comprehensively consider the motion state of each link to make the manipulator reach the target position. In this regard, this study proposes a fast coope
