Space environment risk index construction method and device and storage medium

Abstract

The invention discloses a space environment risk index construction method and device and a storage medium, and the method comprises the steps: firstly determining space environment factors related tothe on-orbit abnormality of a spacecraft; secondly, screening influence intervals of the determined space environment factors; and finally, extracting risk characterization indexes of the space environment and thresholds thereof. The risk characterization index and the threshold thereof obtained through the scheme can more effectively and accurately characterize the space radiation environment risk suffered by the spacecraft, thereby ensuring that the risk characterization index and the threshold thereof can meet the requirements of spacecraft anomaly and space environment correlation construction analysis and spacecraft space weather risk prediction.

Description

technical field [0001] The present invention generally relates to the technical field of on-orbit analysis and data processing of spacecraft space environment effects, and in particular to a construction method, device and storage medium of a space environment risk index. Background technique [0002] The spacecraft in orbit will be affected by the space environment, and the space radiation environment will cause electrostatic discharge, single particle, total dose and other effects on the spacecraft, which will affect the on-orbit operation of the spacecraft. In order to identify and warn of the impact of on-orbit spacecraft anomalies, it is necessary to use the existing spacecraft on-orbit anomaly data combined with the space environment in which the spacecraft is located to carry out data analysis. [0003] The current data analysis methods mainly include: using the time scale to directly correspond to the space environment before and after the abnormal data of the spacec...

Problems solved by technology

[0003] The current data analysis methods mainly include: using the time scale to directly correspond to the space environment before and after the abnormal data of the spacecraft, and judge whether there is an abnormality. This method is more commonly used but the effect is not ideal; This method is relatively universal; the detailed analysis of the spatial environment fluctuations before and after the occurrence of individual significant abnormal events has certain limitations; although there are currently certain data analysis methods, However, in reality, the representation data of the space environment are many and complicated. If no effective space environment factors are selected, it is likely that the analysis will not be able to obtain accurate results.
