This paper presents an innovative multi-sensor relative navigation module conceived to
enable close-proximity operations for on-orbit servicing of small satellites. The module is …

This paper proposes several task space control approaches for complex on-orbit high
degrees of freedom robots. These approaches include redundancy resolution and take the …

Future autonomous spacecraft rendezvous with uncooperative or unprepared objects will be
enabled by vision-based navigation, which imposes great computational challenges …

This paper proposes a simple yet effective approach to learn visual features online for
improving loop-closure detection and place recognition, based on bag-of-words frameworks …

The spacecraft pose tracking control problem for an uncertain pursuer approaching to a
space target is researched in this paper. After modeling the nonlinearly coupled dynamics …

This paper presents a novel decentralized relative navigation algorithm. The relative motion
equations are derived in the Earth-Centered-Inertial frame. The relative measurements …

Multispacecraft cooperative visual 3-D sensing is an essential technique in space-based
optical space situational awareness to acquire the 3-D pose and structure of orbital targets …

Imaging cameras are cost-effective sensors for spacecraft navigation. Image-driven
techniques to extract the target spacecraft from its background are efficient and do not …

Since nanosatellites are spotlighted as a verification platform for space technology, new
studies on on-orbit satellite servicing using nanosatellites are being conducted. This …

This paper describes a concurrent learning approach to relative range estimation by a single
vehicle following a lead vehicle and using only passive, monocular vision for feedback. The …
