Description / Abstract:
This Standard 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.
The Standard can be used to develop calculation techniques based on
different models of Earth's geomagnetic field [1]. 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 spacecrafts and other equipment in the
near-Earth space.
The Standard is valid for calculation 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:
-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.
