Planar Dynamics of Flezible Cables Mounted on Lagrangian Point Satellites
1 IntroductionThe development of high resolution space observatories is critical to the advance of modern astronomy. Space interferometers constructed using multi-spacecraft formations are suitable for demanding tasks such as exosolar planet finding and imaging early cosmic structures. Light collected by individual collector spacecraft within the formation are redirected to a central combiner spacecraft, where the different beams are processed in a way to obtain a high resolution image. During an observation the collector spacecraft must fly in a precise formation and rotate about the observatorys optical axis, and various solutions have been proposed for the formation keeping problem. While space interferometers with a baseline of a few tens of meters can be constructed using truss structures, observatories with a longer baselines can only be realized using tethered or a free flying formations.
