A Sub-Hertz, Low-Frequency Vibration Isolation Platform
NASA’s Jet Propulsion Laboratory, Pasadena, California
Saturday, January 01 2011
This system can be used for vibration isolation in semiconductor manufacturing, for space-based imaging systems, or fine pointing of free-space optical communication transceivers.
One of the major technical problems deep-space optical communication (DSOC) systems need to solve is the isolation of the optical terminal from vibrations produced by the spacecraft navigational control system and by the moving parts of onboard instruments. Even under these vibration perturbations, the DSOC transceivers (telescopes) need to be pointed l000’s of times more accurately than an RF communication system (parabolic antennas).
