Abstract
This paper presents the simulation studies of the dynamics of short tethered satellite system during the deployment phase. The deployment dynamics of the tethered system is dominated by the tether oscillations and the three-dimensional attitude dynamics of the sub-satellite. The dynamic characters of the system are investigated, and probable control strategies that can be adopted for the faithful and hassle-free deployment of the tether are discussed. Tether is proposed to be released with an initial velocity with constant deceleration using tension in tether. Dynamics of a short tether of 10 m length connected to a 10 kg 3U sub-satellite is considered in the study. Deployment with tether in tension and without tension in tether is discussed.
