Le Guiming, Zhao Mingxian and Tian Tian.IntroductionThere are a large number of satellites for communication, meteorology, navigation, etc. in the geostationary orbit. High-energy electrons can induce deep charging of satellites, causing satellite failure. The degree of damage is strongly related to the daily integrated intensity of high-energy electrons. In order to standardize the classification of the daily integrated intensity of electrons with energies above 2 MeV in the geostationary orbit, a special This document. Electrons with energies above 2 MeV in geostationary orbit Daily integral intensity classification1 ScopeThis document specifies the daily integrated intensity levels for electrons above 2 MeV in geostationary orbit. This document applies to the monitoring and early warning of the daily integrated intensity of electrons with energies above 2 MeV in the geostationary orbit.2 Normative referencesThis document has no normative references.3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 geostationary orbit The orbital plane coincides with the Earth's equatorial plane, the orbital period is equal to the Earth's rotation period, and the orbital eccentricity is equal to 0, a geosynchronous orbit. [Source. GB/T 39094-2020, 2.3] 3.2 electron daily integrated intensity Ie The total number of electrons per square centimeter, per steradian, and per day. Note. The unit is per square centimeter spherical degree day [cm2·sr·d]4 Intensity classificationThe daily integrated intensity (Ie) of electrons with energies above 2 MeV in the geostationary orbit should be divided into five levels according to Table 1. Table 1 Daily integrated intensity classification of electrons with energy above 2 MeV in geostationary orbit Strength Grade Strength Description Intensity range (cm 2• sr •d) -1 Level 1 Low Ie< 107 Level 2 107≤Ie< 108 Level 3 High 108≤Ie< 109 Level 4 Extra High 109≤Ie< 2×109 Level 5 ultra-high Ie≥2×109 ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 45560-2025_English be delivered?Answer: Upon your order, we will start to translate GB/T 45560-2025_English as soon as possible, and keep you informed of the progress.
