    This document describes in general terms the spacecraft navigation process at JPL and the institutional elements involved in this effort. It cutlines the major computer and software systems used and indicates the basic ...
  • McCarthy, John; Ferrall, Joseph; Charng, Thomas; Houseman, John (Pasadena, CA : Jet Propulsion Laboratory, 1981-06)
    A technical assessment of the following advanced coal gasification processes: AVCO High Throughput Gasification (HTG) Process; Bell Single-Stage High Mass Flux (HMF) Process; Cities Service/Rockwell (CS/R) Hydrogasification ...
  • Unknown author (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 1981, 1981-07-15)
    Progress in the low cost solar array project during the period February to July 1981 is reported. Included are: (1) project analysis and integration; (2) technology development in silicon material, large area silicon sheer ...
  • 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.
  • 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 ...
  • 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 ...
  • 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.
  • Plaut, J.; Arvidson, R. (1992)
    This paper describes the comparison of image data and derived parameters for the equatorial plains of Venus.
  • 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 ...
  • 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 ...
  • 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 ...
  • Halpern, D. (1992)
    Since July 1987 the Remote Sensing Systems, Santa Rosa, California, routinely computes from first principles the wind speed from Special Sensor Microwave Imager (SSM/I) measurements of the intensity of microwave radiation ...
  • Tawel, R. (1992)
    This paper describes a novel analog Vector Array Processor (VAP) that was designed for use in real-time and ultra-low power image compression applications. This custom CMOS processor is based architectually on the Vector ...
  • Mack, L. (1992)
    This paper describes the calculation of the effect of wall cooling on the instability of a two-dimensional, flat-plate supersonic boundary layer under stratospheric flight conditions at Mach 3 using both the inviscid and ...
  • Halpern, D. (1992)
    The upper-ocean temperature distribution along the Pacific equator from 139 to 103 degrees west was observed in January 1992 with temperature profiles recorded from a ship and inferred from an ocean general circulation ...
  • Ostro, S. J. (1992)
    Planetary radar astronomy is the study of solar system entities (the moon, asteroids, and comets, as well as the major planets and their satellites and ring systems) by transmitting radio signals towards a target and ...
