Space environment (natural and artificial). Cosmic ray and solar energetic particle penetration inward the magnetosphere. Method of determination of the effective vertical cut-off rigidity
空间环境(自然和人工) 宇宙射线和太阳高能粒子向磁层内的穿透 有效垂直截止刚度的测定方法
BS ISO 17520:2016 describes the effective vertical cut-off rigidities of charged particles
for near-Earth space and establishes principal requirements for their calculation. In Annex A, the
calculation technique is verified using a typical example. This International Standard can be used to
develop calculation techniques based on different models of Earth's geomagnetic field. The techniques
are useful for determination of penetrating into the Earth's magnetosphere by charged particle fluxes, as
well as for test and estimations of the impact on spacecraft and other equipment in the near-Earth space.This International Standard is valid for calculating the particle penetration by any of the component
of interplanetary charged particles (Galactic, Solar, and Anomalous) with rigidities above 0,2 GV. The
main goals of the present standardization for the determination of the effective vertical geomagnetic
cut-off rigidities are as follows:provide an unambiguous procedure for calculation of the cut-off rigidities inside of the Earth's
magnetosphere reflecting dependences on geomagnetic disturbances and local time;provide means of estimation of the impact of charged particle fluxes in interpretation and analysis
of space experiments;provide efficient calculations of the transmission functions of low-altitude orbits of spacecraft and
manned space-station;determine impact of solar energetic particle flux on spacecraft instrumentation and astronauts
using results of independent online measurement of interplanetary particle fluxes.Cross References:ECSS-E-ST-10-04C:2008NIMA TR8350.2:1997ISO 16695All current amendments available at time of purchase are included with the purchase of this document.
