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

    Gautier, T. N., 1996, "(abstract) An All Sky Cirrus Confusion Noise Map for WIRE", https://hdl.handle.net/2014/26519, Sagamihara, Japan, JPL Open Repository
    The Wide Field Infrared Explorer (WIRE) is a Small Explorer (SMEX) satellite scheduled for launch in 1998 which will carry out a sky survey of at least 100 square degrees in the wavelength regions of 9-15µm and 21-27µm with spatial resolution of approximately 20 arcsec and sensit...
    (abstract) An Assessment of Electric Propulsion Research, Development, and Application in the United States

    Stephenson, R. Rhoads, 1995, "(abstract) An Assessment of Electric Propulsion Research, Development, and Application in the United States", https://hdl.handle.net/2014/33669, Moscow, JPL Open Repository
    This paper will discuss the development of Electric Propulsion technology in the U.S. from the 1960's to the present. It will summarize the various activities related to arcjets, resistojets, pulsed plasma thrustors, magneto-plasma-dynamic thrustors, ion engines, and more recentl...
    (abstract) An Extensive Search for Interplanetary Slow-mode Shocks: Ulysses
    Dec 15, 1996
    Sakurai, R.; Ho, C. M.; Tsurutani, B. T.; Goldstein, B. E.; Balogh, A., 1996, "(abstract) An Extensive Search for Interplanetary Slow-mode Shocks: Ulysses", https://hdl.handle.net/2014/27364, San Francisco, CA, JPL Open Repository
    Ulysses has accumulated five years of interplanetary solar wind plasma and IMF measurements. These data cover from 1 to approximately 5 AU and all the heliographic latitudes. Based on these data, we perform an extensive search for the slow-mode shocks. We find a considerable numb...
    (abstract) Application of Neural Networks to Hyperspectral Unmixing
    Oct 10, 1994
    Barhen, Jacob; Toomarian, Nikzad, 1994, "(abstract) Application of Neural Networks to Hyperspectral Unmixing", https://hdl.handle.net/2014/33284, Paris, France, JPL Open Repository
    The emergence, in recent years, of hyperspectral sensors provides a tremendous opportunity for advancing the process of detailed and direct remote detection and identification from space of targets or surface materials. Such sensors exploit the uniqueness of the corresponding spe...
    (abstract) Application of Non-coherent Data Types for Deep Space Navigation
    May 15, 1995
    Bhaskaran, Shyam, 1995, "(abstract) Application of Non-coherent Data Types for Deep Space Navigation", https://hdl.handle.net/2014/33422, Greenbelt, MD, JPL Open Repository
    Several options are being examined to reduce the costs of spacecraft and deep space missions. One such option is to fly spacecraft in a non-coherent mode, that is, the spacecraft does not carry a transponder and cannot coherently return a Doppler signal. Historically, such one-wa...
    (abstract) Application of Space Technology to NDE at JPL
    Oct 8, 1996
    Bar-Cohen, Yoseph, 1996, "(abstract) Application of Space Technology to NDE at JPL", https://hdl.handle.net/2014/27480, Los Angeles, CA, JPL Open Repository
    JPL is responsible for the deep space exploration using spacecraft and telerobotic technologies. Since all its missions are one of a kind and hardware dependent, the NDE requirements are significantly more stringent than the ones for aerospace conventional needs. The multidiscipl...
    (abstract) Application of the GPS Worldwide Network in the Study of Global Ionospheric Storms
    Jan 14, 1997
    Ho, C. M.; Mannucci, A. J.; Lindqwister, U. J.; Pi, X.; Sparks, L. C.; Rao, A. M.; Wilsion, B. D.; Yuan, D. N.; Reyes, M., 1997, "(abstract) Application of the GPS Worldwide Network in the Study of Global Ionospheric Storms", https://hdl.handle.net/2014/27505, Santa Monica, CA, JPL Open Repository
    Ionospheric storm dynamics as a response to the geomagnetic storms is a very complicated global process involving many different mechanisms. Studying ionospheric storms will help us to understand the energy coupling process between the Sun and Earth and possibly also to effective...

    A 9 µm 256x256 hand-held quantum well infrared photodetector (QWIP) camera has been demonstrated. Excellent imagery, with a noise equivalent differential temperature (NEƔ) of 26 mK has been achieved. In this presentation, we discuss the development of this very sensitive long wav...
    (abstract) ARGOS: a System to Monitor Ulysses Nutation and Thruster Firings from Variations of the Spacecraft Radio Signal
    Jun 19, 1995
    McElrath, T.P.; Cangahuala, L.A.; Miller, K.J.; Stravert, L.R.; Garcia-Perez, Raul, 1995, "(abstract) ARGOS: a System to Monitor Ulysses Nutation and Thruster Firings from Variations of the Spacecraft Radio Signal", https://hdl.handle.net/2014/33532, Toulouse, France, JPL Open Repository
    Ulysses is a spin-stabilized spacecraft that experienced significant nutation after its launch in October 1990. This was due to the Sun-spacecraft-Earth geometry, and a study of the phenomenon predicted that the nutation would again be a problem during 1994-95. The difficulty of...
    (abstract) Asteroid 4769 Casalia: Intrepretation of Optical Lightcurves Using a Radar-Derived Shape Model
    Oct 31, 1994
    Hudson, R.S.; Ostro, S.J.; Harris, A.W., 1994, "(abstract) Asteroid 4769 Casalia: Intrepretation of Optical Lightcurves Using a Radar-Derived Shape Model", https://hdl.handle.net/2014/34590, Washington, DC, JPL Open Repository
    A 167-parameter, 3-D shape model of Castalia, obtained from inversion of delay-Doppler images, constrained the object's subradar latitude on the date of the observations by defining an annular sky region that contains Castalia's pole. We have used the shape model and nominal Hapk...
