Shallow Encounters' Impact on Asteroid Deflection Prediction and Implications on Trajectory Design
Rodolfo Batista Negri, Antônio Fernando Bertachini de Almeida Prado
Analytical approximations are commonly employed in the initial trajectory design phase of a mission to rapidly explore a broad design space. In the context of an asteroid deflectio…
Autonomous and Robust Orbit-keeping for Small Body Missions
Rodolfo Batista Negri, Antonio Fernando Bertachini de Almeida Prado
This article presents a path-following control law for autonomous orbital maintenance of small body missions. The control law is robust, stable, and capable of controlling only the…
A Circular Restricted n-body Problem
Rodolfo Batista Negri, Antonio Fernando Bertachini de Almeida Prado
This paper introduces the Circular Restricted n-Body Problem (CRNBP), an extension of the bicircular restricted four-body problem (BCR4BP) designed to describe the dynamics of an n…
Study on Autonomous Gravity-assists with a Path-following Control
Rodolfo Batista Negri, Antônio Fernando Bertachini de Almeida Prado
We investigate the autonomous control of gravity-assist hyperbolic trajectories using a path following control law based on sliding mode control theory. This control strategy ensur…
