Abstract

The invention discloses a debris removal-asteroid defense dual-purpose space-based laser system, which is mainly composed of a plurality of space-based laser drive platforms with the same parameters, and each space-based laser drive platform includes a satellite platform, a laser, a detection and aiming system Launching system, array connection device and control system, wherein the array connection device is responsible for connecting with the adjacent satellite platform array connection device when forming a laser drive array, and docking the control lines, and the control system is connected with each subsystem through the bus to control its In the working state, the detection, tracking and launching system detects and discovers space debris and asteroids, performs stable tracking and targeting, and focuses the laser emitted by the laser on the target. The invention generates an impulse to change its orbit through the impulse coupling effect; when there is no threat, it is dispersedly deployed in the LEO orbit and independently performs the active removal of space debris.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a space-based laser system for removing space debris and defending against asteroids through ablation drive. Background technique [0002] Space debris refers to space junk produced by human space activities. At present, the total amount of space debris around the earth is close to 7000t, 43% of which are mainly distributed in the low earth orbit of 400-2000km. They seriously threaten the safety of spacecraft, and it is imperative to mitigate space debris. How to remove space debris has become a hot and frontier issue in the aerospace field. [0003] Asteroid impacts on the earth have occurred frequently in history, causing environmental catastrophes and biological extinctions on the earth many times, and are a major potential threat that may destroy human beings. Preventing asteroids from impacting the earth has become a hot issue of widespread concern in the international ...
