Tether satellite system collision study
Acta Astronautica, 1999A study was performed to determine the probability of collision with resident space objects and untrackable debris for the tether component of the Tethered Satellite System (TSS) after it broke away from the Space Shuttle orbiter (mission STS-75) in February 1996.

Three-dimensional vibrations of tethered satellite systems
Journal of Guidance, Control, and Dynamics, 1991The three-dimensional free vibrations of an orbiter-towed tethered satellite system with nominally vertical tether during stationkeeping phase are studied analytically. The tether is modeled as an elastic continuum with mass and the orbiter and the subsatellite as two concentrated masses.

Tethered Satellite System control system design
3rd Tethers in Space/ Toward Flight International Conference, 1989This paper discusses the control aspects of the Tethered Satellite System mission. The deployer controls system uses length-error and tension-error feedback to control in-plane libration, length, and length rate. The satellite's reaction control system is used to augment tether tension, control rates and attitude about the tether axis, and to damp in ...

Detection of Tethered Satellite Systems
The Journal of the Astronautical Sciences, 2004The detection and identification of tethered satellite systems is a problem of current interest. Most previous studies focused on the detection and identification of one tethered satellite system using the observations of one satellite in the system. Here, we consider the problem of determining which of two or more satellites that are observed to be in

Journal of Spacecraft and Rockets, 1989
T following three papers on tethered satellite systems grew out of session 110 of the AIAA 26th Aerospace Sciences Meeting, held in Reno, Nevada, in January 1988. Interest in such systems, which goes back several years, has been evinced by NASA, various Italian space research activities, and, most recently, by the Japanese. While no tethered spacecraft

On the control of Tethered Satellite Systems
32nd Structures, Structural Dynamics, and Materials Conference, 1991Abstract A mathematical model is proposed for studying the dynamics of the Tethered Satellite System (TSS) consisting of a plate-type space station from which a tether supported subsatellite is deployed or retrieved. The rigid body dynamics of the tether, subsatellite and space station are analyzed accounting for the mass of the tether as well as a ...

An Efficient Model of Tethers for Tethered Satellite Systems
Advances in Astronautics Science and Technology, 2018This paper concerns about modeling of tethered satellites systems (TSS). In this paper, tethers of TSS are modeled as chains of elastic rods connected by rigid joints. A group of spatial vectors are used to describe displacement, orientation and deformation of the rods, which can avoid the coupling of trigonometric functions of Euler angles.
