Recent Developments and Plans from the JPL Analysis Center
• Significant improvement in consistency of JPL’s GPS solutions w.r.t. IGS combined solution starting week 1442.
– Primarily due to use of IGS standards for GPS antenna calibrations.– 80-90% variance reduction in orbit and clock differences.
• JPL updating models and POD strategy in preparation for reprocessing campaign.– Targeting July 2008 to begin reprocessing, starting with 2008.
• New version of GIPSY, version 5.0, to be released June 3, 2008.
