Silver river cosmic ray model selection method and system

Abstract

The invention relates to a silver river cosmic ray model selection method and system, and the method comprises the steps: receiving a silver river cosmic ray model selection instruction, and obtaining analysis data corresponding to each analysis angle from the silver river cosmic ray model selection instruction based on a preset analysis angle. The intensity of the silver river cosmic rays is modulated by a geomagnetic field and solar activity, the analysis range of a silver river cosmic ray model cannot directly include the particle energy range and atomic number range of the silver river cosmic rays, and the silver river cosmic rays can generate different environmental effects on spacecraft materials, electronic components, photoelectric devices and the like. Therefore, various analysis angles are provided in the application, and at least comprise the spacecraft orbit height, the current solar activity period, the particle energy range needing to be analyzed, the atomic number range and the environmental effect analysis. According to multiple analysis angles in the application, the target silver river cosmic ray model conforming to the silver river cosmic ray model selection instruction can be better selected from multiple alternative silver river cosmic ray models.

Description

technical field [0001] This application relates to the technical field of spacecraft space environment design and effect analysis, in particular to a method and system for selecting a galaxy cosmic ray model. Background technique [0002] Galactic cosmic rays are charged particles from outside the solar system, and are composed of charged particles with extremely high energy and low flux. The Galactic Cosmic Ray Model is a spacecraft used to observe and analyze galactic cosmic rays. The galactic cosmic ray model mainly includes model, ISO 15390 (Nymmik) model, Badhwar-O’Neill (BO) model, Davis model, etc. Different galactic cosmic ray models are used in different environments (the environment where the galactic cosmic rays need to be analyzed). Selecting the corresponding galactic cosmic ray model according to the use environment can better play the performance of the galactic cosmic ray model, but there is no unified method in the prior art to select the corresponding g...
