Relative navigation is a key enabling technology for space missions such as on-orbit
servicing and space situational awareness. Given that there are several special advantages …

ABSTRACT The Japan Aerospace Exploration Agency (JAXA) is investigating a cost-
effective active debris removal (ADR) system to remove large debris objects such as rocket …

Abstract Space debris has become a growing problem, and various studies indicate that the
population of space objects has reached a critical density in low Earth orbits (LEO) …

This paper proposes a Pontryagin-based approach to Nonlinear Model Predictive Control
for autonomous guidance and control in spacecraft maneuvering. The proposed approach …

Range-only relative orbit determination for spacecraft proximity operations suffers from a
well-known mirror solution problem in the context of Clohessy-Wiltshire dynamics during …

In space, visual-based relative navigation systems suffer from dynamic illumination
conditions of the target (eclipse conditions, solar glare, etc.) where most of these issues are …

Since the navigation sensors used in angles-only navigation are simple, angles-only
navigation will be a critical enabling technique for spacecraft autonomous rendezvous and …

This paper discusses a system for an End-of-Life (EOL) deorbit service to deorbit a satellite
no longer in operation. The system uses an ablation thrust force generated on the target …

Range-only Initial relative orbit determination (IROD) for natural-periodic relative motion
(periodically coasting flight) during close-in proximity suffers from a mirror-solution (also …

Orbital debris has become an increasingly severe problem, and active debris removal (ADR)
missions are gaining progressively more attention. The first step in an ADR mission would …
