Propagation and reconstruction of re-entry uncertainties using continuity equation and simplicial interpolation

A new journal article by Mirko Trisolini and Camilla Colombo of the COMPASS team in the Journal of Guidance, Control, and Dynamics applies a continuum-based methodology to the propagation of uncertainties in planetary re-entries.

The main highlights of the work are:

  • Direct propagation of the uncertainty density using the continuity equation coupled with the entry dynamics.
  • Reconstruction of the marginal probabilities using a simplex-based interpolation methodology.
  • Comparison of the results with standard Monte Carlo uncertainty propagation methodology.
