Abstract
The work is devoted to reproduction of the 27-day variations of the galactic cosmic rays (GCR) flux, observed in the PAMELA experiment, by simulating the propagation of GCR in the heliosphere. The map of the interplanetary electromagnetic field has been constructed in accordance with the Parker model and measurements of the ACE spacecraft. We have created an algorithm, which numerically solves the motion equation of cosmic rays in that field and reconstructs their trajectory. Charged particles are generated on the edge of the heliosphere, then the particles are traced with help of the numerical algorithm. The initial characteristics of the particles correspond to the uniform and isotropic distribution. As a result of calculations we have obtained the time dependencies of the GCR flux in the near-Earth space for energy 1 GeV.
