Fine guidance technology development for the Shuttle Infrared Telescope Facility (SIRTF) centers upon the use of a single multiple-star-tracking sensor to provide the position information necessary to produce three-axis attitude control signals for precision payload pointing. Development of this guidance technology is a joint effort of the Jet Propulsion Laboratory (JPL) and the Ames Research Center. The JPL effort, described in this paper, is concerned with the development of a Fine Guidance Sensor that employs a high-density charge-coupled imaging device for producing position information signals by using star fields. Multiple star position information produces 3-axis position error signals that are used to update inertial reference gyros. The sensor employs advanced position interpolation algorithms to enhance field-of-view resolution and to correct for optical aberrations inherent in spatially chopped star images resulting from the telescope's movable secondary mirror. Operation of the sensor is under the control of a high-performance microcomputer that provides both autonomy and flexibility in a guidance application. Details of the technology involved in the development of the Fine Guidance Sensor as well as performance data are described in the paper.
