MOCAT-SSEM is a Source-Sink model that predicts the Low Earth Orbit (LEO) space population divided into families using a predefined set of interaction parameters. Thanks to data from the Monte Carlo version of the model (MOCAT-MC), which propagates singularly every object, it is possible to estimate such parameters, assumed as additional stochastic variables. Thus, this paper proposed a new set of parameters so that the new Source-Sink model prediction better fits the computationally expensive and accurate MOCAT-MC simulation. Estimation is performed by extracting stochastic quantities from the space population, which has been analyzed to fit common probability density functions.

  1. The Sustainability of the Leo Orbit Capacity via Risk-Driven Active Debris Removal

    eess.SY 2025-07 reject novelty 4.0 of 10

    A modified debris risk index, FMM, is introduced and claimed to identify high-collision objects better than prior indices, but the validation appears to use the same simulations for both the labels and the rankings.
