Periodic motion in the tethered satellite system

Journal of Guidance, Control, and Dynamics, 1996
The tethered satellite system (TSS) operating in an elliptic orbit may have a periodic motion. The configuration and stability of the limit cycle depend on the control algorithm and the orbital eccentricity. The size of the limit cycle increases as the orbital eccentricity increases.

Development status of first Tethered Satellite System

24th Aerospace Sciences Meeting, 1986
An MOU between NASA and Italian research organizations has assigned the responsibilities for the development, payload integration, launch and operation of a Tethered Satellite System (TSS). The TSS will include a deployer mounted on a Spacelab pallet, science equipment on a customized mission support structure and a satellite connected to the Orbiter ...

Stabilizing tethered satellite systems using space manipulators

Proceedings of IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS'94), 2002
The use of space manipulators to stabilize a two-body tethered satellite system (TSS) during the stationkeeping and retrieval phases, is considered. The uncontrolled motion of the system in the stationkeeping phase is marginally stable, while during the retrieval phase it is unstable.

Tethered Satellite System Deployer Flight Thermal Performance

SAE Technical Paper Series, 1993
<div class="htmlview paragraph">The Tethered Satellite System (TSS) is a Space Shuttle payload that was flown on July 31, 1992. Though anomalies prevented full deployment, the duration of the mission was approximately as planned, so it was possible to assess system thermal performance.

The tethered satellite system - An electrodynamic mission

27th Aerospace Sciences Meeting, 1989
The tethered satellite system, a joint U.S.-Italian project to develop a Space Shuttle-based facility for deploying satellites either radially toward or away from the earth to distances up to 100 km, is described with particular attention given to its first mission (TSS-1).

Control of an Orbiting Platform Supported Tethered Satellite System

IFAC Proceedings Volumes, 1989
Abstract 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 ...

General formulation for N-body tethered satellite system dynamics

Journal of Guidance, Control, and Dynamics, 1996
We derive the equations of motion by using the Lagrangian formulation. The derived equations are valid for large librational motion, variable lengths, and an arbitrary orbits. The elasticity and mass of the tethers are taken into account. Longitudinal and transverse displacements of the tethers are assumed to be small compared to the lengths and are ...

Dynamics and control of tethered satellite systems

Acta Astronautica, 2008
Abstract Dynamics and control of two-body and n -body tethered satellites are considered. At first, nonlinear roll and pitch motions of two-body systems are examined. Then the effects of aerodynamic and electrodynamic forces on the stability of a tethered satellite are discussed. Various control schemes to stabilize the dynamics during retrieval

Nonlinear control of tethered satellite system oscillations

Nonlinear Analysis: Theory, Methods & Applications, 1997
Summary: The control of in-plane transversal vibrations of a tethered satellite system by means of a longitudinal force exerted by subsatellite thrusts is analyzed. A one-mode model is derived for describing the inplane dynamics of such a system.
