GPU-Accelerated Astrodynamics World Models for Spacecraft Rendezvous and Proximity Operations

An open-source, JAX-based International Space Station docking environment supporting parallel GPU simulation of spacecraft orbit and attitude dynamics is introduced and a transformer-based world model is introduced, a transformer-based world model that encodes relative kinematic states and body-fixed camera imagery int...

Chance-Constrained Belief-Space Maneuver Planning for Autonomous Collision Avoidance Under Uncertainty

Increasing conjunction frequency in low Earth orbit places growing pressure on spacecraft operators to determine not only whether an encounter requires mitigation, but whether sufficient information is available to commit to a maneuver. This work formulates this information-action tradeoff as a belief-space planning pr...
