A low-order automatic domain splitting approach for nonlinear uncertainty mapping
Matteo Losacco, Alberto Fossà, Roberto Armellin
This paper introduces a novel method for the automatic detection and handling of nonlinearities in a generic transformation. A nonlinearity index that exploits second order Taylor…
A Multifidelity Approach to Robust Orbit Determination
Alberto Fossà, Roberto Armellin, Emmanuel Delande +2
This paper presents an algorithm for the preprocessing of observation data aimed at improving the robustness of orbit determination tools. Two objectives are fulfilled: obtain a re…
Robust initial orbit determination for short-arc Doppler radar observations
M. Losacco, R. Armellin, C. Yanez +3
A new Doppler radar initial orbit determination algorithm with embedded uncertainty quantification capabilities is presented. The method is based on a combination of Gauss' and Lam…
Multifidelity Orbit Uncertainty Propagation using Taylor Polynomials
Alberto Fossà, Roberto Armellin, Emmanuel Delande +2
A new multifidelity method is developed for nonlinear orbit uncertainty propagation. This approach guarantees improved computational efficiency and limited accuracy losses compared…
