DEBRISK is part of a set of tools developed by CNES in the framework of the French Space Operation Act. It evaluates the survivability of fragments from a satellite entering the Earth’s atmosphere. This software is available for space operators to check the compliance of their vehicles with this technical regulation.

DEBRISK computes trajectories and ablation of fragments from a space vehicle during re-entry. This software uses an object oriented approach. : it assumes the satellite to be a multiple interdependent objects set, modelled by simple forms. Each object is characterized by its geometrical shape, its size, its mass and its material. DEBRISK supplies a list of the surviving objects and their characteristics upon ground arrival. ELECTRA, another CNES tool for compliance with French Space Operation Act, uses this list and the characteristics of fragments to compute corresponding casualty area.
