As the demand for on-orbit maintenance of non-cooperative targets grows, the rapid identification of the mass characteristic parameters of spacecraft has become a research focus within the field. Drawing inspiration from MEV (Mission Extension Vehicle), this paper designs an algorithm that uses a three-degree-of-freedom manipulator to drive an electric thruster as the actuator, achieving on-orbit identification of spacecraft mass characteristics through electric thruster firing and reaction wheel control. The algorithm, based on the least squares method and Gaussian filter, is capable of simultaneously identifying the center of mass position and inertia tensor of the spacecraft while in orbit. The required sensor measurements are limited to the spacecraft’s angular velocity and reaction wheel rotation speed, making it widely applicable. The numerical simulation results demonstrate that the algorithm designed in this paper can rapidly converge under various error conditions and achieve high identification accuracy. This validates the favorable performance of the algorithm, indicating its potential for engineering practicality.
