Geomagnetic storms disrupt space navigation systems such as satellite with rapid and large changes in particle flux. To study the effects of cosmic rays and calculate the rate of faults and errors and provide a suitable shield against them, we need to know the energetic particles flux. In the present work, we have obtained protons flux and energy range by simulating in different solar cycles and in 4 major solar flare events. In the first step of the proton flux simulation, we have used OMEREH. software; We have then compared the obtained data from the simulation with the experimental data from AMS collaboration and they were in a good agreement with each other. In the next step, first we have determined satellite’s coordinates and properties using OMEREH; then we have calculated the flux of energetic protons that collide to a typical satellite in Leo orbit at the time of flares occurrence. The number of solar events increases in solar maximum. Therefore, these analyses should be done carefully and the design should be more significant in long-term space missions.
