Abstract:The dynamic stability of a rotating triangular tethered satellite formation near libration points during the deployment and retrieval stages is investigated. Based on Hill's approximation, a new dynamical formulation for the attitude and orbital motions of the system is developed. Using numerical simulations, parametric studies of the effects of the orbital amplitude, initial rotation rate, tether length, and length rate are performed. It is shown that different initial rotation rates or length rates have almost no impact on the trajectories of the system's centroid. As expected, increasing the initial rotation rate or reducing the length rate can improve the stability of a tethered satellite system. (C) 2014 IAA. Published by Elsevier Ltd. All rights reserved.
