The propagation of energetic particles in the heliosphere is described by the Parker transport equation. It includes the physical processes of diffusion, drift, convection and adiabatic energy changes. For the inner heliosphere the Jovian magnetosphere is the dominant source of energetic electrons. Therefore the so-called Jovian electrons are nearly perfect test particles in order to study transport theories. In this contribution we present model calculations of the electron flux in Parker- and Fisk-type heliospheric magnetic field configurations and compare our results to spacecraft data.
