Embodiment Construction

[0037] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0038] Step 1: Obtain initial information

[0039] like figure 1As shown, firstly, according to the prior information of the serving spacecraft, the center of the enveloping sphere is taken as the center of the serving spacecraft, and its maximum outer diameter r f is the radius of the envelope sphere, determine the envelope sphere of the service spacecraft; at the same time, take the center of the service spacecraft as the coordinate origin O b , determine the coordinate axis vector in a direction parallel to its principal axis of inertia and

[0040] Use the 3D reconstruction technology to reconstruct the 3D model of the space target, and determine the half-cone angle η of the natural safety corridor of the space target, such as figure 2 shown. The center of the three-dimensional model of the space target is the center of the envelope ellipsoid, and th...

Abstract

The invention relates to a guidance strategy for an electromagnetic eddy current racemization process of a space tumbling target, which comprises the following steps of: firstly, determining a guidance scheme according to various information of a service spacecraft and a space target; according to different motion states of the space target, two guidance schemes are provided, and a less-maneuvering, low-complexity and efficient expected trajectory of the space target in any motion state can be generated. Compared with the existing research, the method has the advantages that the trajectory maneuver is small, the complexity is low, and the safety and the high efficiency of the racemization process can be ensured.

Description

technical field [0001] The invention belongs to the technical field of derotation of space tumbling targets, and relates to a guidance strategy for the derotation process of electromagnetic eddy currents of space tumbling targets. The guidance strategy can be applied to the derotation stabilization of various space tumbling targets. Background technique [0002] In the past 60 years, humans have launched about 12,070 satellites and generated about 29,520 space debris. Increasingly, objects of space debris are considered a serious hazard for current and future space missions. Among them, the greater the mass of the target, the greater the risk of collision with existing operational satellites. However, currently large debris targets, such as runaway satellites and abandoned rocket bodies, account for more than 90% of the total mass of orbiting space debris. Therefore, aggressive removal of these large debris targets can greatly reduce the risk of collisions in space. [00...
