The earths magnetic field modulates the energy spectra of charged particle radiation reaching a satellite from outside the magnetosphere. This report describes how a transmission function is calculated that modulates the radiation environment in the interplanetary medium to obtain the orbit-averaged radiation environment at the skin of any spacecraft in a circular orbit. It is found that the location of the electronics package within the spacecraft may affect the soft upset rate.
