The JPL Open Repository (JOR) replaced the JPL Technical Report Server (TRS) in 2023. It is a repository for digital copies of technical publications authored by JPL employees. It includes journal articles (the Final Accepted Version), meeting papers, presentations, and other publications cleared for external distribution from 1992 to the present. It also includes research datasets from 2022 on.

Years covered: 1992 to the present.
  • 1992-2021 records were originally on the JPL Technical Report Server (TRS) on Dspace system; those records were migrated to Dataverse in 2022.
  • Records with publication date 2022 or later are native to the Dataverse.
  • Data sets: 2022 to present
  • There are a few pre-1992 records. Those were added to the system on a case-by-case request basis.

  • Persistent IDs (PIDs):
  • 1992-2021 records have Handles
  • 2022 and later records have Digital Object Identifiers (DOIs).
    • Featured Dataverses

    In order to use this feature you must have at least one published dataverse.

    Publish Dataverse

    Are you sure you want to publish your dataverse? Once you do so it must remain published.

    Publish Dataverse

    This dataverse cannot be published because the dataverse it is in has not been published.

    Design of a Low Gravity Simulator for Performing Non-Equilibrium Investigations near the Lambda Transition of ^4He
    Jan 1, 1993
    Israelsson, U. E.; Duncan, R. V., 1993, "Design of a Low Gravity Simulator for Performing Non-Equilibrium Investigations near the Lambda Transition of ^4He", https://hdl.handle.net/2014/35381, ['Bulletin of the American Physical Society', 'Seattle, Washington'], JPL Open Repository
    A design is presented of a low gravity simulator where a magnetic field gradient is employed to oppose the hydrostatic pressure effects of gravity. It appears feasible to reduce the effective gravity environment of the helium in the cell by about two orders of magnitude. The corr...
    InGaAs Detectors for Miniature Infrared Instruments
    Jan 1, 1993
    Krabach, T.N.; Staller, C.; Dejewski, S.; Cunningham, T.; Herring, M.; Fossum, E.R., 1993, "InGaAs Detectors for Miniature Infrared Instruments", https://hdl.handle.net/2014/34839, ['SPIE: Infrared Systems Engineering', 'Los Angeles, CA'], JPL Open Repository
    In the past year, there has been substantial impetus for NASA to consider missions that are of relatively low cost as a trade off for a higher new mission launch rate. To maintain low mission cost, these missions will be of short duration and will use smaller launch vehicles (e.g...
    Channel and Terminal Description of the ACTS Mobile Terminal
    Jan 1, 1993
    Abbe, B. S.; Agan, M. J.; Girardey, C. C.; Jedrey, T. C., 1993, "Channel and Terminal Description of the ACTS Mobile Terminal", https://hdl.handle.net/2014/35072, Pasadena, CA, JPL Open Repository
    The Advanced Communications Technology Satellite (ACTS) Mobile Terminal (AMT) is a proof-of-concept K/Ka-band mobile satellite communications terminal under development by NASA at the Jet Propulsion Laboratory. Currently, the AMT is undergoing system integration and test in prepa...
    HEAO 3 Observations of the Galactic Center 511 keV Line

    Mahoney, W.; Ling, J.; Wheaton, W., 1993, "HEAO 3 Observations of the Galactic Center 511 keV Line", https://hdl.handle.net/2014/35291, JPL Open Repository
    This paper describes improved analysis algorithms which enabled HEAO 3 data to be reexamined for an assumed point source at the Galactic center.
    Winter Sea Ice Mapping From Multi-Parameter Synthetic Aperture Radar Data
    Jan 1, 1993
    Rignot, E.; Drinkwater, M., 1993, "Winter Sea Ice Mapping From Multi-Parameter Synthetic Aperture Radar Data", https://hdl.handle.net/2014/35088, JPL Open Repository
    This paper presents examples of quantitative improvements in classification accuracy of six winter ice conditions using SAR data resulting from the combination of multiple polarizations and frequencies.
    The Effects of Correlated Noise in Phased-Array Observations of Radio Sources
    Jan 1, 1993
    Dewey, R., 1993, "The Effects of Correlated Noise in Phased-Array Observations of Radio Sources", https://hdl.handle.net/2014/35944, UNKNOWN, JPL Open Repository
    Arrays of radio telescopes are now routinely used to provide increased signal-to-noise when obseving faint point sources. However, calculation of the achievable sensitivity is complicated if there are sources in the field of view other than the target source. These additional sou...
    Variation of Great Lakes Water Levels Derived from Geosat Altimetry
    Jan 1, 1993
    Morris, C. S.; Gill, S. K., 1993, "Variation of Great Lakes Water Levels Derived from Geosat Altimetry", https://hdl.handle.net/2014/35507, UNKNOWN, JPL Open Repository
    A technique for using satellite radar altimetry data to estimate the temporal variation of the water level in moderate to large inland bodies of water (lakes, in particular) is described.
