Space junk removal satellite device

Abstract

The invention discloses a space junk removal satellite device which comprises a satellite body and a task execution module. The satellite body comprises a first structure box, a power module, a navigation module, an orbit control module, a flight control module, a wireless communication module and a solar cell array, the power module, the navigation module, the orbit control module, the flight control module and the wireless communication module are arranged in the first structure box, the first structure box is a cube, and all the faces of the box are fixed through mechanical structures; andthe task execution module comprises a second structure box, a task control module, a detection recognition module, a capture module, a smashing module, a transporting module and a laser ablation module, the task control module, the detection recognition module, the capture module, the smashing module, the transporting module and the laser ablation module are arranged in the second structure box, the second structure box is a cube, the left side face of the second structure box is a fixed face mechanically locked to the satellite body, and the remaining five faces are each of a deformable structure and can be unfolded and folded within the range from -60 degrees to 60 degrees. The device can capture and remove small-size space junk, and the space junk containing a conductive material can beablated through the laser ablation module and then secondarily used to supply energy to the laser ablation module.

Description

technical field [0001] The invention belongs to the research field of satellite body control technology, and in particular relates to a space garbage cleaning satellite device. Background technique [0002] Space junk, also known as space debris, comes from a variety of sources. For example, various defunct artificial satellites, abandoned rocket propeller wreckage, fragments formed by the explosion or collision of various satellite bodies, tiny mechanical parts, and even garbage left by astronauts accidentally during space operations, etc. Space junk can be divided into three categories according to its diameter: space junk over 10 centimeters can be monitored by instruments, and their number is about 19,000; junk between 1 centimeter and 10 centimeters cannot be tracked by instruments, and it is estimated that in About 200,000 pieces can cause inductive discharge of internal sensitive components, and even cause structural damage to the satellite body; while space junk wit...

AI Technical Summary

Problems solved by technology

The amount of space junk is increasing at a rate of 5% per year, and in recent years it has been increasing at a rate of 40% per year. As the amount of space junk continues to increase, the probability of collisions between these debris is also increasing, resulting in an avalanche effect. When the amount of debris accumulates to a certain level, it will make it impossible to carry out space activities, and the near-Earth space will completely lose its use value

[0004] Disclosed in the prior art is the method that utilizes tethered space robot to clean up space junk, but this method has following shortcoming: the one, can only capture large-sized space junk, can't capture smaller size debris; The 2nd, can only catch space junk, No function to clean up space junk
