Abstract: 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.

Abstract: Disclosed are a system and a method for capturing a space target. The system includes a plurality of capturing devices, a delivery device, a launching device, and a deceleration and recovery device, each of the plurality of capturing devices is configured to be launched into a target orbit to capture a defunct space target, the delivery device is configured to deliver, along a preset delivery trajectory, each of the plurality of capturing devices to a first preset location in the launching device, the launching device is configured to launch each of the plurality of capturing devices located at the first preset location into the target orbit to capture the defunct space target, and the deceleration and recovery device is configured to decelerate each of the plurality of capturing devices after it is launched and flies a preset distance.
