Pretrained Approximators for Low-Thrust Trajectory Cost and Reachability
Zhong Zhang, Giacomo Acciarini, Dario Izzo +2
Low-thrust trajectory design relies heavily on repeated evaluations of fuel consumption and transfer feasibility, which require expensive optimal control solutions. In this work, w…
EclipseNETs: a differentiable description of irregular eclipse conditions
Giacomo Acciarini, Francesco Biscani, Dario Izzo
In the field of spaceflight mechanics and astrodynamics, determining eclipse regions is a frequent and critical challenge. This determination impacts various factors, including the…
Guidance and Control Networks with Periodic Activation Functions
Sebastien Origer, Dario Izzo
Inspired by the versatility of sinusoidal representation networks (SIRENs), we present a modified Guidance & Control Networks (G&CNETs) variant using periodic activation functions…
Closing the Gap Between SGP4 and High-Precision Propagation via Differentiable Programming
Giacomo Acciarini, Atılım Güneş Baydin, Dario Izzo
The Simplified General Perturbations 4 (SGP4) orbital propagation method is widely used for predicting the positions and velocities of Earth-orbiting objects rapidly and reliably.…
