Detection and estimation of spacecraft maneuvers for catalog maintenance
Laura Pirovano, Roberto Armellin
Building and maintaining a catalog of resident space objects involves several tasks, ranging from observations to data analysis. Once acquired, the knowledge of a space object need…
Design and Guidance of a Multi-Active Debris Removal Mission
Minduli Wijayatunga, Roberto Armellin, Harry Holt +2
Space debris have been becoming exceedingly dangerous over the years as the number of objects in orbit continues to rise. Active debris removal (ADR) missions have garnered signifi…
Team theAntipodes: Solution Methodology for GTOC11
Roberto Armellin, Laurent Beauregard, Andrea Bellome +7
This paper presents the solution approach developed by the team "theAntipodes" for the 11th Global Trajectory Optimization Competition (GTOC11). The approach consists of four main…
Exploiting Scaling Constants to Facilitate the Convergence of Indirect Trajectory Optimization Methods
Minduli C. Wijayatunga, Roberto Armellin, Laura Pirovano
This note develops easily applicable techniques that improve the convergence and reduce the computational time of indirect low thrust trajectory optimization when solving fuel- and…
HO distribution in the disc of HD 100546 and HD 163296: the role of dust dynamics and planet--disc interaction
L. M. Pirovano, D. Fedele, E. F. van Dishoeck +3
[Abridged] Far-infrared observations with Herschel revealed a surprisingly low abundance of cold-water reservoirs in protoplanetary discs. On the other hand, a handful of discs sho…
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…
