JPL Status Report, SCIGN Annual Meeting, 4/26/2004

Overview

• GIPSY Processing status

• NASA REASoN Project Status

JPL Status Report, SCIGN Annual Meeting, 4/26/2004

Processing

• Bias fixing strategy– 5-7 Clusters per day

• CPU intensive• Sensitivity to station outages

– 1 Cluster per day constructed from baselines• Distributable across many CPUs• Insensitive to station outages

• Developed and tested last year• Implemented in April 2003• Moving to web services for antenna metadata• New GIPSY version in Nov. 2003

JPL Status Report, SCIGN Annual Meeting, 4/26/2004

Solutions

• Complete through March 31, 2004.– Available on internet– Free network

• Raw solutions• Loose covariance

– Accounts for frame noise

JPL Status Report, SCIGN Annual Meeting, 4/26/2004

REASoN Goals

• Apply modern IT methodology within SCIGN to:– Produce and disseminate higher-level data

products to a larger community• Scientists• Government agencies (Federal, State, and Local)• Surveyors• GIS professionals

• Product levels adopted by PBO

JPL Status Report, SCIGN Annual Meeting, 4/26/2004

REASoN Goals• Build on current capabilities within SCIGN for data archiving,

information systems, and data analysis to disseminate the following products:– Geodetic position time series– Crustal motion models– Strain rate maps– Geologic fault models– Near-real-time earthquake response information– Geodetic reference systems for precise GIS and surveying

• Improve capabilities in– Archiving– End-user interfaces– Delivery mechanisms– Data modeling

• Open source project based on a redundant, multi-tiered “Virtual Archive” for GPS applications.

JPL Status Report, SCIGN Annual Meeting, 4/26/2004

How we are organized• Around Four systems

– Product Input• Seamless Archive• Web services

– GPS Data Processing• GAMIT and GIPSY

– Product Generation• QOCA Based

– Product Output• Virtual Archive• Web services

– Meta data– Products

• Plus two NASA requirements – NASA SEEDs participation

• Standards Working Group– Open Source Project

• Virtual Archive

JPL Status Report, SCIGN Annual Meeting, 4/26/2004

A High Level Requirement

• Need• Processing centers and processes use the same input data

• Goal• All processing retrieves data from a common source

• Objective• Seamless Archive• Web services• Pull data at time of analysis• Push results into archive• Pull products from archive for distribution
