Vibroimpact Dynamics of a Tethered Satellite System [PDF]

open access: yesShock and Vibration, 2017
This paper presents the vibroimpact dynamics of an in-plane tethered subsatellite caused by sudden braking during deployment or retrieval. The full dynamics of the subsatellite are composed of its free-flight and the instantaneous impacts.

Analysis of the Motion of a Tether-Perturbed Satellite [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2003
The motion of each satellite in a tethered satellite system is non-Keplerian in the Earth's gravitational field. In this paper, the tether perturbation force is formulated and compared with the perturbation force due to the Earth's oblateness.

Dynamics and rebound behavior analysis of flexible tethered satellite system in deployment and station-keeping phases

open access: yesDefence Technology, 2022
The tether deployment of a tethered satellite system involves the consideration of complex dynamic properties of the tether, such as large deformation, slack, and even rebound, and therefore, the dynamic modelling of the tether is necessary for ...

Application of Hamilton Principle in the control of Tethered Satellite System Pendular Motion [PDF]

open access: yesINCAS Bulletin, 2018
The control of a tethered satellite system pendular motion is done by application of Hamiltonian equation of motion on a control design method known as planar H tracking. In this case, the reference motion is considered a natural planar motion.
