The present disclosure provides a multi-arm spacecraft model predictive control method based on the mixture of Gaussian processes, equipment, and a medium. Model predictive control has excellent performance in dealing with complex nonlinear systems such as multi-arm spacecrafts with various constraints, and is widely applied to ground robots, unmanned aerial vehicles, autonomous driving and other practical scenarios. Therefore, a task space controller is designed based on the model predictive control in the present disclosure. Besides, in order to enhance the anti-interference capability of the present disclosure, an interference model is established and compensation is carried out in the model predictive control by utilizing the characteristics of small training data volume and high training speed in the mixture of Gaussian processes. Finally, a thrust distribution method is designed to complete platform control. The method provided by the present disclosure is convenient and intuitive in design and has relatively high practicability.

Disclosed are a method, a device, an apparatus for capturing a non-cooperative target using a space robotic arm, and a non-transitory storage medium, and relates to the technical field of on-orbit servicing. The method is applied to a space robotic arm with a magnetic capture device as an end actuator. The method includes: establishing a magnetic attractive force model for the magnetic capture device, determining a magnetic attractive force characteristic of the magnetic capture device based on the magnetic attractive force model, determining a capture strategy for the non-cooperative target based on the magnetic attractive force characteristic of the magnetic capture device, capturing the non-cooperative target according to the capture strategy, and determining whether the non-cooperative target is captured based on a preset determination condition.

Disclosed are a method, a device and a non-transitory storage medium. The method includes: deploying a detection satellite to fly in one detection orbital plane opposite to the satellites in the large-scale constellation, to sequentially detect satellites flying in one target orbital plane of the large-scale constellation in a manner that an approach distance between the detection satellite and a satellite being detected is within a set detection distance, transmitting the detection satellite from the one detection orbital plane to another detection orbital plane in virtue of Earth oblateness perturbation, so as to sequentially detect satellites flying in another target orbital plane of the large-scale constellation in a manner that the approach distance between the detection satellite and a satellite being detected is within the set detection distance, and stopping the detection satellite from detecting until all satellites of the large-scale constellation have been detected.
