This International 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. This International
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 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 transmissio...
