The Challenge of Pointing Stability and Accuracy in the Space Interferometer Mission (SIM)
Jet Propulsion Laboratory
2001鈥�02
SIM is an orbiting interferometer telescope capable of relative star measurements 100 times more accurate than ever before.卢鈥� Specifically, the team is devising a technique for measuring the spacing between telescopes, measuring changes in distance to an accuracy of 100 picometers, or 1 angstrom, roughly the size of a hydrogen atom.
