A method for identifying the source of disintegrated debris based on orbital data

Abstract

The invention discloses a method for identifying the source of disintegrated debris based on orbital data, comprising: calculating the orbital data of the disintegrated debris; using the orbital data of the disintegrated debris to screen the orbital range of the parent body of the disintegrated debris to obtain a set of suspected disintegrated parent bodies; The number of orbital elements screens the geometry of the orbit surface to obtain the suspected disintegration time of each suspected parent body; calculate the average intersection distance between each suspected disintegrated parent body and each disintegrated fragment at the respective suspected disintegrated time, and take the suspected parent body with the smallest intersection distance as the real disintegrated parent body. Utilizing the invention, it is possible to quickly determine the source body of the debris when the space object disintegrates. This is the first time in our country to fully and comprehensively expound the method of identifying the source of disintegrated debris. The correctness of the method is illustrated through examples, which is of great significance to correctly perceive the changes in the space debris environment and take corresponding measures.

Description

technical field [0001] The invention relates to the technical field of space debris monitoring and early warning, in particular to a method for identifying the source of disintegrated debris based on orbital data, which is suitable for identifying the source of debris after the disintegration of earth-orbiting satellites or rocket wreckage. Background technique [0002] Orbital Surface Spherical Geometry. The disintegration debris and the parent body of the disintegration debris have a specific geometric relationship at the moment of disintegration, so the parent body's perigee argument and parent body's true perigee angle at the time of disintegration (disintegration position) can be determined by the variation of the debris inclination and the right ascension of the birth node The inclination angle with the parent body is calculated. That is, the disintegration time of the parent body can be obtained by calculating the orbital surface prediction of the disintegrating pare...

Problems solved by technology

However, there is no introduction of relevant content in the current literature. The main reasons for the analysis are: (1) The source identification of disintegrated debris is a key technology for the processing of space object monitoring data. (2) The method of identifying the source of disintegrated debris is different from the monitoring equipment of the country / organization, and the analysis and processing methods are also different; (3) After the monitoring equipment is built in other countries, the content of this research will be of great significance , but currently there are few countries with large-scale space object monitoring and cataloging management capabilities, and there are few corresponding research and published papers
