Dim star fringe tracking demonstration on SIM's system testbed-3The main testbed objective is to demonstrate nanometer class stability of fringes in the dim star, or science, interferometer while using path length & angle feed-forward control, and while the instrument is integrated atop a flight-like flexible structure. This document addresses completion of the Path Length Feed Forward milestone, which requires at least 40 dB of external delay rejection at some frequency between 0.1 and 1.0 Hz.
