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 include 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.

    Chen, Chien-Chung; Homayoon Ansari; Lesh, James R., 1993, "Precision Beam Pointing for Laser Communication System Using a CCD-based Tracker", https://hdl.handle.net/2014/35138, Orlando, Florida, USA, JPL Open Repository
    Spatial acquisition and precision beam pointing functions are critical to spaceborne laser communication systems. A recent system study indicated that a single high bandwidth CCD detector can be used to perform both spatial acquisition and tracking functions. Compared to previous...
    The Parametrized Post-Newtonian Gravitational Redshift

    Krisher, T. P., 1993, "The Parametrized Post-Newtonian Gravitational Redshift", https://hdl.handle.net/2014/35215, Physical Review D, JPL Open Repository
    A derivation of the gravitational redshift effect to order c ^(-4) is presented. The calculation isperformed within the framework of the parametrized post-Newtonian formalism for analyzing metrictheories of gravity, which includes corrections to second- order in the Newtonian pot...
    Solar Cycle Variation of Interplanetary Disturbances Observed as Doppler Scintillation Transients
    Apr 9, 1993
    Woo, R., 1993, "Solar Cycle Variation of Interplanetary Disturbances Observed as Doppler Scintillation Transients", https://hdl.handle.net/2014/35209, Journal of Geophysical Research, JPL Open Repository
    Interplanetary disturbances characterized by plasma that is more turbulent and/or moves faster than the background solar wind are readily detected as transients in Doppler scintillation measurements of the near-Sun solar wind.
    Cirrus and Future Space Based Astronomy

    Gautier, T. N., 1993, "Cirrus and Future Space Based Astronomy", https://hdl.handle.net/2014/35845, Tucson, AZ, JPL Open Repository
    Astronomical observations from space make possible observations of sensitivity and spatial resolution impossible in the past. This increase in sensitivity will both make possible the observation of new phenomena and will bring observations against limitations not encountered befo...
    Stability of Small Grains in HII Regions and Reflection Nebulae

    Werner, M.W.; Gauthier, T. N. III.; Cawlfield, T., 1993, "Stability of Small Grains in HII Regions and Reflection Nebulae", https://hdl.handle.net/2014/35549, Tucson, AZ, JPL Open Repository
    We have analyzed IRAS data to assess the relative amounts of small and large grains in HII regions and reflection nebulae. Our most important finding is that no evidence for small grain destruction is seen in reflection nebulae, even for [high] values of the radiation energy dens...
