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.

    Delete Dataverse

    Are you sure you want to delete your dataverse? You cannot undelete this dataverse.

    Improved Ephemerides of Pluto
    Jan 1, 1993
    Standish, E., 1993, "Improved Ephemerides of Pluto", https://hdl.handle.net/2014/35648, UNKNOWN, JPL Open Repository
    The history of the Pluto ephemerides created at JPL is given. The uncertainties of present and possible future ephemerides are illustrated, and it is shown how rapidly the error grows for any present-day ephemeris of Pluto which is extrapolated into the future - tens of thousands...

    Imperceptible to human senses, California continues to deform every day at a rate comparable to the growth of fingernails. Convection in the mantle under the Earth's solid crust forces continental-size
    An Algorithm for State-Space Frequency Domain Identification Without Windowing Distrtions
    Jan 1, 1993
    Bayard, D. S., 1993, "An Algorithm for State-Space Frequency Domain Identification Without Windowing Distrtions", https://hdl.handle.net/2014/36637, UNKNOWN, JPL Open Repository
    An algorithm is presented for identifying state space models from frequency domain data. The main advantage of this approach is that it avoids windowing distortions associated with other frequency domain methods.
    Frequency Swept Diode-pumped Single Frequency TM,Ho:YLiF Laser for spaceborne Doppler Lidar
    Jan 1, 1993
    McGuckin, B.T.; Menzies, R.T.; C.Esproles, 1993, "Frequency Swept Diode-pumped Single Frequency TM,Ho:YLiF Laser for spaceborne Doppler Lidar", https://hdl.handle.net/2014/36562, Anaheim, California, USA, JPL Open Repository
    Optical heterodyne experiments involving the photomixing of two single frequency, deode-pumped thulium holmium yttrium lithium flouride lasers are described. Operated in external frquency stabilization loops, the lasers exhibit 1MHz short term stability, and are photomixed and of...
