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.

    Pseudo-Coherent Demodulation for Mobile Satellite Systems
    Jun 16, 1993
    Divsalar, Dariush; Simon, Marvin K., 1993, "Pseudo-Coherent Demodulation for Mobile Satellite Systems", https://hdl.handle.net/2014/35304, Pasadena, California, USA, JPL Open Repository
    This paper proposes three so-called pseudo-coherent demodulation schemes for use in land mobile satellite channels. The schemes are derived based on maximum-likelihood (ML) estimation and detection of an N-symbol observation of the received signal.

    An active K/K-band antenna array is currently under develoment for NASA's ACTS Mobile Terminal (AMT). The AMT task will demonstrate voice, data, and video communications to and from the AMT vehicle in Los Angeles, California, and a base station in Cleveland, Ohio, via the ACTS sa...
    Stochastic Performance Modeling and Evaluation of Obstacle Detectability With Imaging Range Sensors
    Jun 15, 1993
    Matthies, Larry; Grandjean, Pierrick, 1993, "Stochastic Performance Modeling and Evaluation of Obstacle Detectability With Imaging Range Sensors", https://hdl.handle.net/2014/35395, New York, New York, USA, JPL Open Repository
    In this paper, we address this issue for imaging range sensors by dividing the evaluation problem into two levels: quality of the range data itself and quality of the obstacle detection algorithms applied to the range data.
