The Jet Propulsion Laboratory (JPL) has a long history of processing global GPS data for various geodetic and
orbit determination applications, and serves as an Analysis Center for the International GNSS Service. In this
paper, we describe recent developments in the GPS data processing software system at JPL, GIPSY-OASIS, and
the derived GPS data products. We detail the resulting improvements in accuracy of the primary products, namely
the estimates of the precise GPS orbits and clocks, Earth orientation parameters, and zenith troposphere at the
GPS sites, as well as the impact on various geodetic and orbit determination applications. We provide details of
the changes to the models and capabilities of the GIPSY-OASIS software system, and describe modifications to
the JPL products that are provided to the international community.
