JPL Update Danan Dong Michael Heflin Sharon Kedar Brian Newport Frank Webb JPL Status Report, SCIGN Annual Meeting, 4/26/2004

Overview • GIPSY Processing status • NASA REASo. N 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

REASo. N • • • Reminder of Our Goals How we are organized A High Level Requirement High Level Architecture Baseline Schedule Status JPL Status Report, SCIGN Annual Meeting, 4/26/2004

REASo. N 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

REASo. N 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 JPL Status Report, SCIGN Annual Meeting, 4/26/2004

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

Baseline Schedule (draft) • Key milestones for the remainder of CY 04 are: – Approved Task Plan based on negotiated funding profile (ASAP) – High level system requirements definition and design (Jul 04) – Design and development of modifications to QOCA for combined geodetic time series (Level-1) production software (Dec 04) – Design and development of automated GPS processing interfaces with GDPSES (Dec 04) • Key milestones for CY 05 - CY 08 are: – Design, development, and implementation of automated Level 1 data products (Jul 05) – Design and development of modifications to QOCA for combined velocity field (Level-2) production software (Dec 05) – Design, development, and implementation of automated Level 2 data products (Jul 06) – Design and development of modifications to QOCA for geophysical parameter (Level-3) production software (Dec 06) – Design, development, and implementation of automated Level 3 data products (Jul 07) – Integrate Level-3 products with independent data products (Dec 07). – Incorporate PBO data into production process (Jul 08) – Deliver Adaptive Seamless Achive (Jul 08) – Deliver GPS Explorer (Jul 08) – Deliver Spatial Services (Jul 08) – Deliver Open Source Virtual Archive (Jul 08) JPL Status Report, SCIGN Annual Meeting, 4/26/2004

Status • Organized into initial teams • Worked most of the high level architecture • Working requirements and definitions of interfaces for CY 04: – Processing – Archive – Web services • Working formats – Internal product and data sharing – Prototyped XML schema and formats for metadata and time series products • Product generation – Testing QOCA against GLOBK • Loosely constrained agrees to sub-millimeter level JPL Status Report, SCIGN Annual Meeting, 4/26/2004 – Initial modifications to QOCA for S/T filter has begun

Status • Project library – Document sharing web site for team • Configuration control • Password protected • https: //scign-lib. jpl. nasa. gov • NASA – Currently on startup funds – Draft task plan near completion for remaining funds • PBO – Initial discussions have received a “Ho-Hum” response JPL Status Report, SCIGN Annual Meeting, 4/26/2004
