Embodiment 1

[0032] This embodiment provides an active and passive combination of space debris self-awareness system, such as Figure 1~2 As shown, the space debris self-perception system and a host star are relatively static in the cosmic space, that is, as figure 1 As shown, the space debris self-aware system is installed on the main star 10, or as figure 2As shown, the space debris self-sensing system is installed on a micro-nano satellite 30, and the micro-nano satellite 30 is accompanied by the main star 20. The space debris self-sensing system includes a super large field of view visible light camera 12, a radar 14 , an information processing module 13 and a steering mechanism 11, wherein: the super large field of view visible light camera 12 and the radar 14 are installed on the steering mechanism 11, and the steering mechanism 11 drives the super large field of view visible light camera 12 and the The radar 14 rotates; the super-large field of view visible light camera 12 is used...

Embodiment 2

[0041] This embodiment provides an active-passive combination space debris self-sensing method, the space debris self-sensing method includes: the space debris self-sensing system and a main star 10 (20) are relatively stationary in space, and the space debris self-sensing method In the perception system, the information processing module 13 controls the rotation of the steering mechanism 11 to drive the super-large field of view visible light camera 12 to passively search for space debris in the universe in all directions, and sends the passive search results to the information processing module 13; The information processing module 13 judges whether there is said threatening space debris according to the passive search result, and if there is a threat, then continues to track. When the distance between the space debris and the main star is within 50km, the radar 14 will determine the distance between the main star and the main star. 10 (20) threatening space debris in space w...

Abstract

The present invention provides an active-passive combination space debris self-sensing system and method, and a satellite system, which uses a super-large field of view visible light camera to passively search for space debris at a long distance, and uses radar to actively track space debris at close range after finding threatening space debris. Search, discover, and track space debris that threatens to collide through a combination of active and passive methods. The information processing module controls the rotation of the steering mechanism to drive the super-large field of view visible light camera to passively search for space debris in all directions of the universe, and sends the search results to the information processing module; judge whether there is a threat to space debris, and if there is a threat, continue Tracking, when the distance between the space debris and the main star is within 50km, the radar will actively track the threatening space debris in space, and send the tracking result to the information processing module; the information processing module judges whether the main star shelter is needed according to the tracking result If there is any space debris that threatens the above, if so, then remind the main star to avoid it.

Description

technical field [0001] The invention relates to the technical field of spacecraft, in particular to an active-passive combination space debris self-sensing system and method, and a satellite system. Background technique [0002] The number of space debris in space is increasing every year, especially in recent years, which poses a serious threat and damage to the safe operation of spacecraft in orbit, and once a collision occurs, the wreckage and debris will cause even worse space conditions. environment, posing a greater threat to the safety of space activities. At present, 94% of the objects in orbit are space debris with no use value. Conventional monitoring methods for space debris can be divided into two types: ground-based monitoring and space-based monitoring. Ground-based observation is easily restricted by weather, geographical location and time, and has limited monitoring range, poor detection timeliness, slow data update rate, and At present, the ground can only...
