This paper discusses the development of a ground based experimental environment that can mimic the libration dynamics of tethered satellite systems. The setup consists of an Air-Bearing Inclinable Turntable (A-BIT), whose inclination and rotation rate can be adjusted independently. Appropriate scaling factors help compare the tethered system in the experiment to that in orbit, both of which experience vastly different magnitudes of forces. The two scenarios also differ in their physical parameters including the length of the tether, the mass of the satellite, and the tension along the tether. The scaling factors are used to compare

Kang, Junjie; Zhu, Zheng Hong (CSME-SCGM, 2018-05)A typical and useful way to derive the dynamics equation of the tethered systems is by means of the Lagrange’s equations and various dynamic models of different tethered missions are established by the Lagrangian formulation. ...
Siewnarine, Vishal (2016-09-20)Space debris has become an increasingly larger concern for aerospace travel and exploration. One idea to control the space debris population is to de-orbit defunct satellites using a space tether system. A space tether ...
Quine, Brendan; Seth, R. K.; Zhu, Z. H. (Elsevier, 2009-04-19)Space tethers have been investigated widely as a means to provide easy access to space. However, the design and construction of such a device presents significant unsolved technological challenges. We propose an alternative ...
