1 January 1969 Telescope Fine Guidance
Author Affiliations +
A fine guidance experiment is discussed which is concerned with the improvement of pointing stability in space to accuracy in the order of .01 arc second. This need has become apparent to realize the potential of large (120") diffraction limited telescopes in space. Stability in this order over many hours is required to permit long time integration of the energy from dim and distant stars. The telescope upon which the experiment is based has a completely self-contained attitude control system, and in floated or non-mechanical suspension the telescope will practically constitute an independent space vehicle within its range of motion.
