Convex Trajectory Optimization via Monomial Coordinates Transcription for Cislunar Rendezvous
Omar Regantini, Ethan R. Burnett, Antonio Rizza +2
This paper proposes a nonlinear guidance algorithm for fuel-optimal impulsive trajectories for rendezvous operations close to a reference orbit. The approach involves overparameter…
Modular pipeline for small bodies gravity field modeling: an efficient representation of variable density spherical harmonics coefficients
Antonio Rizza, Carmine Buonagura, Paolo Panicucci +1
Proximity operations to small bodies, such as asteroids and comets, demand high levels of autonomy to achieve cost-effective, safe, and reliable Guidance, Navigation and Control (G…
Gradient based reachability analysis for goal-oriented guidance. Application to Eros proximity operations
Antonio Rizza, Francesco Topputo
The recent growing interest in small solar system bodies such as asteroids and comets for scientific inspection, exploitation of resources, and planetary defense reasons is pushing…
Comparison of uncertainty propagation techniques in small-body environment
Niccolò Michelotti, Antonio Rizza, Carmine Giordano +1
Close-proximity exploration of small celestial bodies is crucial for the comprehensive and accurate characterization of their properties. However, the complex and uncertain dynamic…
