TL;DR: It is demonstrated, as a major novel contribution, how friction between the net and a tumbling target allows reducing its angular motion, stabilizing the system and allowing safer towing operations, giving engineering answers to most challenging open points to lead to a ready to flight solution.

04 Sep 2012TL;DR: The paper presents the design, characterization and testbed setting up of a possible general purpose solution: a net, shut from an active satellite that embraces the debris element, closes around it and drag it to the disposal position in space thanks to a tethered connection.
Abstract: The space debris removal and generation containment in Earth orbits is a well-known and urgent issue to be faced to mainly preserve the safety of the current and future active space systems. From an active removal system design point of view, the more the general purpose it is the more cost effective would be. On the other side, the more general purpose it is, the less practically effective it may turn to be. In fact, a general purpose removal system design should intervene on objects completely different in configuration, materials and possibly in dimensions such as fragments, entire/parts-of dismissed satellites and third stages/fairing elements. Moreover, elements to be managed do not cooperate and have a complex, free, not completely known dynamics. The paper presents the design, characterization and testbed setting up of a possible general purpose solution: a net, shut from an active satellite that embraces the debris element, closes around it and drag it to the disposal position in space thanks to a tethered connection.

TL;DR: This paper systematically introduces a novel geostationary orbit (GEO) space debris removal system called dexterous tethered space robot (DTSR), and describes its design and a typical mission scenario, and presents its two core technologies in detail.
Abstract: In this paper, we systematically introduce a novel geostationary orbit (GEO) space debris removal system called dexterous tethered space robot (DTSR). The DTSR has three notable characteristics: dexterity, lightweight, and cost effectiveness. We first describe the system's design and a typical mission scenario, and then present its two core technologies (vision-based pose measurement and coordinated controller design) in detail. Finally, we present the extensive simulations and ground semiphysical experiments to verify that the DTSR is a feasible solution to effectively remove the GEO space debris.

TL;DR: In this paper, a maneuverable tethered space net (MTSN) is proposed for space debris capture and removal, and an adaptive second-order supertwisting sliding mode control scheme is employed for the stability control of the net.
Abstract: The issue of space debris capture and removal has become extremely urgent, due to the huge amounts of passive (or active) space debris along operational orbits. As a promising solution, space tethered net is low cost and executable. Based on this kind of nonmaneuverable space net, a new solution for space debris capture and removal is proposed in this paper, named maneuverable tethered space net (MTSN). We first describe the structure of the MTSN in detail, and then give a typical mission scenario. Then, the kinematics and dynamics model of the MTSN is derived under some basic conclusions of single space tether. An appropriate initial condition is decided after the analysis of releasing characters, including folding pattern, shooting angle, and shooting velocity. Considering the longitudinal elasticity of tether and the uncertainties from space environment, an adaptive second-order supertwisting sliding mode control scheme is employed for the stability control of the MTSN. Finally, we verify the controller by both theoretical proof and numerical simulations.
