Dynamics of a flexible tethered satellite system utilising various materials for coplanar and non-coplanar models

This paper discusses the development of mathematical models for a flexible tethered satellite system (TSS) in both planar and co-planar states. The flexible tethered satellite system consists of three rigid bodies with two flexible tethers, each connecting two rigid bodies with one located in the ce...
