Likelihood Scouting Via Map Inversion For A Posterior-Sampled Particle Filter
Simone Servadio
An exploit of the Sequential Importance Sampling (SIS) algorithm using Differential Algebra (DA) techniques is derived to develop an efficient particle filter. The filter creates a…
Parameters Evolution in Source-Sink Space Population Evolutionary Models
Erin Ashley, Carla Simon Sanz, Simone Servadio +1
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 fr…
Propagation of Uncertainty with the Koopman Operator
Simone Servadio, Giovanni Lavezzi, Christian Hofmann +2
This paper proposes a new method to propagate uncertainties undergoing nonlinear dynamics using the Koopman Operator (KO). Probability density functions are propagated directly usi…
Uncertainty Propagation and Filtering via the Koopman Operator in Astrodynamics
Simone Servadio, William Parker, Richard Linares
The Koopman Operator (KO) provides an analytical solution of dynamical systems in terms of orthogonal polynomials. This work exploits this representation to include the propagation…
Threat Level Estimation From Possible Break-Up Events In LEO
Simone Servadio, Daniel Jang, Richard Linares
The NASA Standard Break-Up Model models collisions and explosions in space, which identifies the future distribution of debris. Given a possible break-up event, this work analyses…
A New Monte-Carlo Model for the Space Environment
Daniel Jang, Davide Gusmini, Peng Mun Siew +4
This paper introduces a novel Monte Carlo (MC) method to simulate the evolution of the low-earth orbit environment, enhancing the MIT Orbital Capacity Analysis Tool (MOCAT). In rec…
A Lambert's Problem Solution via the Koopman Operator with Orthogonal Polynomials
Julia Pasiecznik, Simone Servadio, Richard Linares
Lambert's problem has been long studied in the context of space operations; its solution enables accurate orbit determination and spacecraft guidance. This work offers an analytica…
A Koopman-Operator Control Optimization for Relative Motion in Space
Simone Servadio, Roberto Armellin, Richard Linares
A high order optimal control strategy implemented in the Koopman operator framework is proposed in this work. The new technique exploits the Koopman representation of the solution…
A Koopman Operator Tutorial with Othogonal Polynomials
Simone Servadio, David Arnas, Richard Linares
The Koopman Operator (KO) offers a promising alternative methodology to solve ordinary differential equations analytically. The solution of the dynamical system is analyzed in term…
Dynamics Near the Three-Body Libration Points via Koopman Operator Theory
Simone Servadio, David Arnas, Richard Linares
This paper investigates the application of the Koopman Operator theory to the motion of a satellite about a libration point in the Circular Restricted Three-Body Problem. Recently,…
