Aerogravity-Assist Maneuvering of a Tethered Satellite System
Journal of Spacecraft and Rockets, 2004Two new implementations of a tethered satellite system to provide aeroassist during a planetary flyby are investigated. In each mission scenario the interaction of the Martian atmosphere with an aerodynamic lifting surface, which is tethered to an orbiter, is used to perturb the flight path of the system. The aerodynamic forces generated by interacting

Research and development of tethered satellite cluster systems
Proceedings. 2000 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2000) (Cat. No.00CH37113), 2002We propose the concept of tethered satellite cluster systems, as an application of the RoboSat clusters. The system consists of some satellites joined by tethers, and keeps and changes the constellation with tension/length control of the tethers to perform various orbit service missions.

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

Modeling and Simulation of Flexible Tethered Satellite System
2018 15th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE), 2018This paper presents the dynamic equations of a flexible tethered satellite system in a circular orbit. The tether is modelled as a combination of point masses connected with massless rods. Through this model the flexibility and distributed mass of tether are considered.

A DISCRETIZED MODEL FOR THE DYNAMICS OF A TETHERED SATELLITE SYSTEM AND APPLICATIONS
Mathematical Models and Methods in Applied Sciences, 1991This paper deals with a simulation of a tethered satellite system where a discretized model of the cable is considered. The characteristics of a few space discretization procedures are compared while investigating the dynamics of two physically relevant models, namely the Space Pendulum and the Space String.

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 ...

Estimation and control of tethered satellite systems
Journal of Guidance, Control, and Dynamics, 1995This paper describes the analysis of a tethered system during the station-keeping phase. The system is composed of two small satellites connected by a long tether. The satellites are modeled as particles, and the tether is represented by eight rigid, massive rods. The angles between adjacent elements can vary with time.

Control of the vibrations of a tethered satellite system
Journal of Applied Mathematics and Mechanics, 2000The authors discuss the landing capsule leaving the orbit by means of a tether without using jet engines. This system is modelled by symbolic dynamical equations of multibody systems. Active damping is provided by an actuator between the main body and the tether. The control parameters are optimized.

The Italian participation to the tethered satellite system
Acta Astronautica, 1982Abstract In this paper the Tethered Satellite System (TSS) is presented in its various aspects of scientific and applicative utilization, program development and technical realization. 1. First, the basic features of TSS are introduced, together with its potential applications which have been preliminarily proposed to NASA. 2.
