As space debris has become a cause of concern for space operations around Earth, active
debris removal and satellite servicing missions have gained increasing attention. Within this …

Abstract Space debris is often uncooperative and unresponsive, necessitating the
understanding of its motion for successful post-capture control in an active debris removal …

Tethered systems, such as tethered harpoons or nets, are promising methods to capture
uncooperative space debris, but suffer from complicated post-capture dynamics and control; …

The close observation of orbiting objects with Cubesats can efficiently support a wide range
of applications, such as the inspection of defunct satellites for preparing active debris …

This paper investigates the six-degrees-of-freedom (6-DOF) rendezvous and docking issue
with an uncontrolled target for a servicing spacecraft under thruster misalignment and …

The release and retrieval of a CubeSat from a big spacecraft is useful for the external
inspection and monitoring of the big spacecraft. However, docking maneuvers during the …

Using nanosatellites to reclaim a failed satellite needs nanosatellites to attach to its surface
to take over its attitude control function. This is challenging, since parameters including the …

This paper addresses the approaching trajectory control problem for the final phase of non-
cooperative spacecraft proximity operations in the presence of disturbances and even input …

The on-orbit service technology is expected to play an important role in space debris
removal missions. In order to capture and remove space debris objects, servicing satellites …

Exploration technology roadmaps have been developed by ESA in the past few years and
the edition of 2015 has just been released. In the context of Moon exploration initiatives and …
