TBE has developed and uses a variety of environments in various threat and end-to-end simulations. We have implemented over 30 different standard atmospheric profiles (pressure, density, and temperature as functions of altitude) in physics-based trajectory and signature models. We have also developed and integrated gravity models ranging from Newtonian central force to quadrupole moment to the EGM-96 spherical harmonic gravity model.

TBE uses industry-standard radiation transport tools, such as LOWTRAN, MODTRAN, MOSART, SAMM, and similar software, to model the near-Earth radiative environment.
