Global monitoring method for large spacecraft based on bionic micro-nano constellation

Abstract

The invention discloses a large-scale spacecraft global monitoring method based on a bionic micro-nano constellation. The method includes: releasing the micro-nano constellation through a honeycomb-like release mechanism; through a micro-nano constellation space layout control method based on a bionic potential function, Make the constellation evenly distributed on the enveloping sphere with the spacecraft as the center; adjust the attitude of the constellation to realize the monitoring of the spacecraft or its external environment; receive the monitoring data of the constellation, summarize and process it, and send it to the micro-nano constellation Monitoring instructions; determine the satellites that need to be recovered through the constellation life prediction and fault diagnosis, and recover them through the recovery mechanism. Other satellites in the constellation will change their positions under the action of the potential function to make up for the vacancy of the monitoring field of view of the exiting satellites, and realize the reconstruction of the constellation . The monitoring method of the present invention has a large monitoring field of view, comprehensive information, high monitoring efficiency, and strong environmental adaptability, and can realize the non-dead-angle patrol inspection of large spacecraft by monitoring constellations, and realize three-dimensional, panoramic, and real-time global inspection of large spacecraft Monitor the effect.

Description

technical field [0001] The invention relates to a large-scale spacecraft global monitoring method based on a bionic micro-nano constellation, and belongs to the technical field of aerospace systems. Background technique [0002] The performance and technical level of large spacecraft are constantly improving. Due to the complex system composition, high development cycle and high cost, it has become an important task in the field of space technology to ensure the long-lasting, stable and healthy in-orbit operation of large spacecraft in complex space environments. This is an important issue, and improving monitoring technology is an effective means to solve it. [0003] At present, the monitoring and escorting of large spacecraft is usually carried out by the sensors carried by the spacecraft itself or a single micro-satellite released by the spacecraft to perform orbital inspection and follow-up. However, a series of ground and space demonstration experiments and Applied re...

Problems solved by technology

[0006] The problem to be solved by the present invention is that, aiming at the problem that the existing method for monitoring spacecraft flying around a single star cannot meet the needs of panoramic three-dimensional real-time monitoring, a method for global monitoring of large-scale spacecraft based on bionic micro-nano constellations is proposed. The method is based on the function of bionic potential function, so that the configuration of the constellations is transformed and evenly distributed on the enveloping spherical surface with the spacecraft as the center.
