Introduction

There 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 classification

4 Intensity classification

The 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< 2x109 Level 5 ultra-high Ie>=2x109
