Spacecraft space environment abnormity and influence forecast method and system, storage medium, and server

Abstract

The invention provides a spacecraft space environment abnormity and influence forecast method and system, a storage medium, and a server. The method comprises the following steps: acquiring abnormitydata of a spacecraft in in-orbit running and the corresponding space environment data; constructing correlativity of the spacecraft abnormity and space environment data based on the abnormity data andthe space environment data; and forecasting the spacecraft abnormity based on the real-time collected space environment data and the correlativity of the spacecraft abnormity and the space environment data. Through the spacecraft space environment abnormity and influence forecast method and system and the storage medium provided by the invention, the correlativity of the spacecraft in-orbit abnormity and the space environment is acquired through various abnormity data of the in-orbit spacecraft, thereby realizing the spacecraft abnormity and influence early-warning based on the space environment, and laying foundation for the space weather guarantee service of the spacecraft in the in-orbit running period.

Description

technical field [0001] The present invention relates to the technical field of spacecraft space environment, in particular to a method, system, storage medium, and server for forecasting abnormality and impact of spacecraft space environment. Background technique [0002] There have been nearly 40 years of research on the relationship between spacecraft on-orbit operation and the space environment. With the advancement of science and technology and the accumulation of experience, the impact of the space environment on the orbital operation of spacecraft is mainly manifested in the following aspects: [0003] (1) During geomagnetic storms, the number and energy of charged particles around the earth increase. When a spacecraft passes through these high-energy environments, phenomena such as surface charging / discharging and deep layer charging / discharging may occur that seriously threaten the safety of the spacecraft; [0004] (2) The bombardment of solar high-energy particles...

AI Technical Summary

Problems solved by technology

[0003] (1) During geomagnetic storms, the number and energy of charged particles around the earth increase. When a spacecraft passes through these high-energy environments, phenomena such as surface charging / discharging and deep layer charging / discharging may occur that seriously threaten the safety of the spacecraft;

[0004] (2) The bombardment of solar high-energy particles may lead to single-event events, thereby changing the software instructions of the computer, causing misoperation, and even causing physical damage to microchips;

[0005] (3) During a magnetic storm / substorm, the upper atmosphere of the earth will be heated and expanded, thereby significantly increasing the drag force on the spacecraft, causing the orbit of the spacecraft to drop abnormally, and even causing the spacecraft to crash;

[0006] (4) During a strong magnetic storm, the magnetopause will be compressed into the synchronous orbit, and the attitude control of geosynchronous orbit satellites may be affected;

[0007] (5) Radio communication may be affected by the space environment. Satellite-ground communication needs to penetrate the ionosphere, but the inhomogeneity of the ionosphere will cause obvious satellite-ground communication signal flickering, and the communication quality will decline significantly or even fail.
