    Thomas, J. B. (Pasadena, CA : Jet Propulsion Laboratory, 1989-02)
    This report focuses on second-order digital phase-locked loops (DPLLs) with uniformly sampled input, an amplitude-insenstive phase extractor and a conventional loop filter.
  • The Modern Role of Visual Observations of Comets 
    Larson, S. M.; Edberg, S. J.; Levy, D. H. (1989-09)
    This paper reviews the role of past and future visual observations in cometary research. The Strengths and limitations of visual observations are explored for the benefit of both investigators who might have to use them ...
  • Terrestrial Response to Eruptive Solar Flares: Geomagnetic Storms 
    Gonzalez, W. (1992)
    This paper describes the interplanetary structures that are associated with the large-amplitude and long-duration negative B subscript z fields that are found in the sheath field and/or driver gas regions of the shock and ...
  • Left-Slip Evolution of the North Owl Creek Fault System, Wyoming, During Laramide Shortening 
    Paylor, E.; Yin, A. (1992)
    This paper decribes a study that is part of an ongoing investigation of the kinematics of major faults in the western Owl Creek Mountains, central Wyoming.
  • Comparison of Goldstone and Magellan Radar Data in the Equatorial Plains of Venus 
    Plaut, J.; Arvidson, R. (1992)
    This paper describes the comparison of image data and derived parameters for the equatorial plains of Venus.
  • Lunar Base Siting 
    Staehle, R. L.; Burke, J. D.; Snyder, G. C.; Dowling, R.; Spudis, P. D. (1992)
    There are widely dispersed lunar sites of interest for known and potential resources, selenology and observatories. Discriminating characteristics include certain geologic and topographic features, local mineralogy and ...
  • Mission Analysis for Laser Interferometer Space Antenna (LISA) 
    Hechler, F.; Folkner, W. M. (1992)
    The interplanetary orbits of three pairs of spaceprobes carrying laser interferometer antennae are designed such that their miutual distances, i.e., the lengths of the interferometer arms remain nearly constant. The pairs ...
  • Smart Focal-Plane Technology for Micro-Instruments and Micro-Rovers 
    Fossum, Eric R. (1992)
    It is inevitable that micro-instruments and micro-rovers for space exploration will contain one or more focal-plane arrays for imaging spectroscopy or navigation. In this paper, we explore the state-if-the-art in focal-plane ...
