Dispersions of the State Variables During Re-Entry
The uncertainties of the atmosphere cause deviations from the precalculated re-entry flight path data. Modelling the density by a diffusion process the vehicle’s altitude h, arc length s, velocity v and flight pass angle γ referenced to the local horizon (Fig. 4.1) become stochastic processes too.
