Tethers for Small Satellite Applications

This paper begins with a sketch of the history of space tether concepts and then describes the four tether orbital flight tests flown in 1992-94 (TSS-1, SEDS-1, PMG, and SEDS-2). It reviews currently funded flight experiments and studies aimed at near-term flights. Next it provides a brief tutorial on some key aspects of space tether concepts. Finally it homes in on issues and applications relevant to small satellites, and gives specific examples of typical mission scenarios, tradeoffs, benefits, and costs.
