Therefore, the radiation fluence environment received by the satellite depends on its launch date Period, orbit and cycle of operation vary. For satellite design, the most important thing is the worst case and confidence level of radiation fluence. By understanding these conditions, it is possible to optimize design. Although radiation belt models to date can distinguish solar maxima from minima, they have difficulty dealing with short-term and long-term waves. move. Procedures for obtaining worst-case and confidence levels for radiation fluences are defined using quasi-dynamic models of the Earth's radiation belts. The space environment uses a quasi-kinetic model to obtain Earth Worst case and confidence level procedures for radiation fluences1 ScopeThis paper presents the particle injection (in terms of orbit and design lifetime) exposure to a spacecraft using a model that describes the dynamic fluctuations of the radiation belts. Quantity calculation method. The quasi-dynamic Earth radiation belt model determines dynamic changes according to input parameters (various indices), and the input parameters are selected as Parameters that are readily available and highly correlated with dynamic changes in the Earth's radiation belts. This document applies to areas such as spacecraft design.2 Normative referencesThis document has no normative references.3 Terms and DefinitionsThe following terms and definitions apply to this document. The terminology databases used by ISO and IEC for standardization are as follows. 3.1 L value The distance between the center of the earth and the point where the lines of force intersect with the magnetic equator, in units of Re (radius of the earth). 3.2 B/B0 The value normalized by the minimum value of magnetic induction intensity at the position of the magnetic equator. 3.3 Kp and ap Global geomagnetic activity levels based on 3h measurements from 13 ground stations. Note. The range of ap value is 0~400, the unit is 2nT. Kp is basically the logarithm of ap, with a scale from 0 to 9 expressed in 1/3 of the unit (e.g., 5-= ,50=5,5=5 ). The daily index (Ap) is obtained by averaging 8 ap values per day, and the index Ap can have the same value as the ap considerable value. 3.4 Solar wind speed solarwindspeed SWS The speed at which the sun emits particle streams is usually used as an input parameter for the external source field model. Note. The solar wind speed is usually about 350km/s. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GBZ42244-2022_English be delivered?Answer: Upon your order, we will start to translate GBZ42244-2022_English as soon as possible, and keep you informed of the progress.
