RKF's satellite phone tool is used to analyze the effects of the dynamic human 3d models and electromagnetic propagation on a phone's performance margin and 3d far field pattern.

Impairments taken into account by the satellite phone analysis tool include: 3d motion position/orientation, the human head and hand (along with the phone itself), user motion (e.g. walking in a field or toward a building), 3d electromagnetic propagation, reflection/absorption and 3d propagation models.
