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.

    Probe Compensation Characterization in Cylindrical Near-Field Scanning
    Jun 27, 1993
    Hussein, Ziad A.; Rahmat-Samii, Yahya, 1993, "Probe Compensation Characterization in Cylindrical Near-Field Scanning", https://hdl.handle.net/2014/34852, Ann Arbor, MI, JPL Open Repository
    This paper presents a useful computer simulation methodology to properly characterize the role of probe compensation in cylindrical near-field scanning. The methodology is applied to a linear test array antenna and has been applied to other antenna configurations.
    Learning Search Control Knowledge for Deep Space Network Scheduling

    Gratch, Jonathan; Chien, Steve; DeJong, Gerald, 1993, "Learning Search Control Knowledge for Deep Space Network Scheduling", https://hdl.handle.net/2014/35258, Amherst, MA, USA, JPL Open Repository
    While the general class of most scheduling problems is NP-hard in worst-case complexity, in practice, for specific distributions of problems and constraints, domain-specific solutions have been shown to perform in much better than exponential time.

    Huang, J.; Densmore, A.; Tulintseff, A.; Jamnejad, V., 1993, "Downsizing Antenna Technologies for Mobile and Satellite Communications", https://hdl.handle.net/2014/34760, Ann Arbor, MI, JPL Open Repository
    Due to the increasing and stringent functional requirements (larger capacity, longer distances, etc.) of modern day communication systems, higher antenna gains are generally needed. This higher gain implies larger antenna size and mass which are undesirable to many systems. Conse...

    A research program is underway to establish the feasibility of fabricating 15 cm diameter ion engine optics from polycrystalline diamond film. Because of its high thermal conductivity, low CTE, and low sputter yield, diamond film has the potential of mitigating life limiting and...
