The low-cost and short-lead time of small satellites has led to their use in science-based
missions, earth observation, and interplanetary missions. Today, they are also key …

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 …

Accumulating space debris edges the space domain ever closer to cascading Kessler
syndrome, a chain reaction of debris generation that could dramatically inhibit the practical …

Existing active debris removal methods that require physical contact with the target have
applicability limitations depending on the maximum angular momentum that can be …

Autonomous spacecraft critically depend on on-orbit inspection (ie, relative navigation and
inertial properties estimation) to intercept tumbling debris objects or defunct satellites. This …

Many objects in space are passive, with unknown inertial properties. If attempting to dock
autonomously to an uncooperative object (one not equipped with working sensors or …

We present the localization approach for Astrobee, a new free-flying robot designed to
navigate autonomously on the International Space Station (ISS). Astrobee will accommodate …

Relative Measurements systems represent a key technology for next generation space
missions that require proximity operations between satellites. Before on-orbit validation, the …

Target tracking plays an important role in the construction, operation, and maintenance of
the space station by the robot, which puts forward high requirements on the accuracy of …

Vision devices are currently one of the most widely used sensory elements in robots:
commercial autonomous cars and vacuum cleaners, for example, have cameras. These …
