    12. System Capabilities Fully automated ingestion, postprocessing, and distribution Over 3000 individual image products delivered daily Over 100 datasets delivered daily 24 hour Met7 and Met5 coverage Acquisition and distribution of all visible NOAA, DMSP, and SeaWifs passes

    13. System Characteristics (1) Dual Sparc Ultra-2 (puck & miranda) Ingest platforms Antenna control X-session hosting Dual Sparc Ultra-60 (titania & oberon) Postprocessing Distribution Intel 2xPIII 1.1Ghz Linux (snowblind) Scripted postprocessing and distribution

    14. System Characteristics (2) All Sparc platforms run Solaris 2.7 Linux platform runs stock RedHat 7.2 distribution All platforms run Terascan 3.1.2 Metsat (pdus) decryption SeaWiFS capture and processing DMSP/KG-44 control

    15. Signal Processing Discussion (1) Ultra 2s Ingest and initial processing All data is transferred via RCP to the Ultra-60s for local processing Some data is also FTPed to clients and the Supplemental Weather Radar (SWR) Host in-house X sessions for Teravision users; NFS crossmounts permit access to all available data

    16. Signal Processing Discussion (2) Ultra-60s Finished products to web servers Subsets to FTP clients Full datasets to Linux platform Linux platform (snowblind) Generates all products accessible via http://www.nemoc.navy.mil/cgi-bin/sat_page.pl Static thumbnails and scaled imagery for looping to improve browser response times

    17. Signal Processing Discussion (3) snowblind (continued) True-color SeaWiFS processing Transparent and false-color overlay briefing products Ingest and postprocessing of datasets received remotely at the Sigonella, Sicily facility and delivered via FTP in near-real time All products generated via custom scripting based on Terascan and the netpbm utilities

    31. System Performance Evaluation Extremely stable; > 140 days uptime routine reboots not required Flexible, simple scripting via cshell and the Terascan functions GUI-based utilities ease administrative tasks but dont get in the way of low-level functionality Comprehensive hypertext on-line documentation Responsive technical support

    32. Conclusion Terascans proven ability to perform in a mission-critical role has rendered it invaluable to US Navy operational support in the European theater. Together with the Linux operating system, it leverages open-source software and commodity hardware into a cost-effective, powerful, and flexible configuration, easily able to meet the requirements of a high-volume, high-throughput mission.
