Libration dynamics and stability of electrodynamic tethers in satellite deorbit
This paper studies libration dynamics and stability of deorbiting nano-satellites by short and bare electrodynamic tethers. A critical aspect of satellite deorbit by an electrodynamic tether is to… Expand

Upper limits from the LIGO and TAMA detectors on the rate of gravitational-wave bursts
We report on the first joint search for gravitational waves by the TAMA and LIGO collaborations. We looked for millisecond-duration unmodeled gravitational-wave bursts in 473 hr of coincident data… Expand

Fractional order sliding mode control for tethered satellite deployment with disturbances
TLDR
This paper proposes a fractional order sliding mode control for the deployment of tethered space systems with the consideration of uncertainty of external disturbances and unmodeled system dynamics. Expand

Elastodynamic analysis of low tension cables using a new curved beam element
In this paper, we address and overcome the difficulties associated with the use of the classic cable theory to treat low tension cables by developing a new three-noded locking-free nonlinear curved… Expand

Long term dynamics and optimal control of nano-satellite deorbit using a short electrodynamic tether
Abstract This paper studies the long term dynamics and optimal control of a nano-satellite deorbit by a short electrodynamic tether. The long term deorbit process is discretized into intervals and… Expand
