Space non-cooperative target capture system and method based on micro-nano satellite cluster

Abstract

The invention discloses a space non-cooperative target capture system and method based on a micro-nano satellite cluster. The capture system comprises a main satellite, a sight satellite subgroup anda work satellite subgroup; the main satellite is used for carrying, releasing and recycling the sight satellite subgroup and the work satellite subgroup, according to the measuring information of thesight satellite subgroup, data fusing and calculating are carried out, according to the data fusing and calculating result, the work satellite subgroup is commanded and dispatched to get close to, attach to and manage the space non-cooperation target, work satellites are used for being attached to the attaching surface of the space non-cooperation target through rail and posture cooperative control manner, sight satellites are used for obtaining whole or local images of the space non-cooperation target, the relative pose relation scheme between the work satellites and the space non-cooperationtarget and the pose relation of the sight satellites relative to the main satellite in the space and sends the obtained information to the main satellite through the inter-satellite wireless communication, and the capture system can be suitable for multiple different capture tasks.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a space non-cooperative target acquisition system and acquisition method based on micro-nano satellite clusters. Background technique [0002] At present, there are more than 19,000 trackable man-made objects flying around the earth, of which there are only more than 2,000 spacecraft in normal operation. non-cooperative target. Due to the loss of control, the non-cooperative target in space is in a state of attitude roll on the orbit, and its orbit changes randomly with the action of space complex perturbation force. On the one hand, non-cooperative space targets will occupy space orbital resources, making the newly launched spacecraft have no suitable orbit selection; on the other hand, it may also collide with normal spacecraft, thus bringing potential safety hazards to the operation of the latter. Therefore, how to capture non-cooperative targets in space and transfer the...

Problems solved by technology

However, these methods have many shortcomings, which make their practical application in orbit difficult.

For example, when the space flying net is capturing the target, it is easy to cause the failure of the flying net to expand due to the nonlinearity, kinks and entanglements of the rope net structure; Cooperative target; when the space manipulator captures the target, it is easy to cause the target and the body to collide due to insufficient torque of the manipulator, resulting in mission failure

In addition, programs such as space flying nets and space harpoons can only be used once, which leads to high costs for capturing non-cooperative targets in space
