WebDec 1, 2024 · The main tether is connected to the tug at one end and branches into multiple sub-tethers connecting to the edges of the debris at the other ends. This debris-tether-tug (DTT) system is able to mitigate the attitude disturbances of the debris, and can be considered as a simplification of tether net. WebAFIT/DS/ENY/06-04 Abstract In recent years, much thought has been given to the use of small satellite clus- ters with distributed sensors to provide large virtual apertures, which have significant weight and packaging efficiencies. One proposed method to maintain the formation shape is with the use of tethers. This dissertation assesses the utility of …
