This final work presents a new tool for the rapid calculation of the Minimum Orbital Intersection Distance (MOID) evolution between objects orbiting the Earth. It is primarily intended as a filtering stage (the second filtering stage proposed by Hoots) for the assessment of the collision risk between a selected object and a huge number of detected and potentially dangerous space debris. The tool combines: •??The speed of a new orbit propagator developed by the Space Dynamics Group of the Technical University of Madrid (SDG-UPM) called DROMO (SDG-DROMO); •??The rapidity of MOID computation given by a new available routine developed by the same group (SDG-MOID).
