Abstract:  We present an overview of the recent developments in the
processing of global GPS data at the Jet Propulsion Laboratory IGS
Analysis Center. We also describe changes that we will implement before
we begin to reprocess these data for our submission to the IGS
reprocessing campaign. 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 also provide details of the changes to
the models and capabilities of the GIPSY-OASIS software system,
particularly with regards to the new capabilities of the version 5.0
release of GIPSY.
