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.

    Hechler, F.; Folkner, W. M., 1992, "Mission Analysis for Laser Interferometer Space Antenna (LISA)", https://hdl.handle.net/2014/26393, UNKNOWN, JPL Open Repository
    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 move relative to each other in an equilateral triangle.
    Optimum Detection of Frequency-Hopped Signals

    This paper derives and analyzes optimum and near-optimum structures for detecting frequency-hopped (FH) signals with arbitrary modulation in additive white Gaussian noise. The principalmodulation formats considered are M-ary frequency-shift-keying (MFSK) with fast frequency hoppi...
    Terrestrial Response to Eruptive Solar Flares: Geomagnetic Storms
    Jan 1, 1992
    Gonzalez, W., 1992, "Terrestrial Response to Eruptive Solar Flares: Geomagnetic Storms", https://hdl.handle.net/2014/36708, JPL Open Repository
    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 are thought to be the main cause of the intense storms.

    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 petrology, solar illumination, view of Earth and the celestri...
    Validation of Special Sensor Microwave Imager Monthly-Mean Wind Speed From July 1987 to December 1989
    Jan 1, 1992
    Halpern, D., 1992, "Validation of Special Sensor Microwave Imager Monthly-Mean Wind Speed From July 1987 to December 1989", https://hdl.handle.net/2014/36704, Transactions on Geoscience and Remote Sensing, JPL Open Repository
    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 emitted at the ocean surface. The accuracy of monthly-mean...
