  As part of the dynamical analysis carried out within the Horizon 2020
ReDSHIFT project, this work analyzes the possible strategies to guide low
altitude satellites towards an atmospheric reentry through an impulsive
maneuver. We consider a fine grid of initial conditions in semi-major axis,
eccentricity and inclination and we identify the orbits that can be compliant
with the 25-year rule as the target of a single-burn strategy. Besides the
atmospheric drag, we look for the aid provided by other dynamical perturbations
- mainly solar radiation pressure - to facilitate a reentry. Indeed, in the
case of typical area-to-mass ratios for objects in LEO, we observed that
dynamical resonances can be considered only in combination with the atmospheric
drag and for a very limited set of initial orbits. Instead, if an area
augmentation device, as a solar sail, is available on-board the spacecraft, we
verified that a wider range of disposal solutions become available. This
information is exploited to design an improved mitigation scheme, that can be
applied to any satellite in LEO.
