Simulation of single tether systems

A simulation of an orbiting single tether system composed of two subsatellites and a connecting tether is developed. The dynamics of the tethered system is modelled using a series of mass beads interconnected by springs and dash pots. The bead model allows the tether to become slack (no tension) and to deform to an arbitrary shape. Simulation results are presented and discussed for two types of motion: (1) tether vibrations and (2) end mass retrieval.
