  1. LRGS Enhancements for LRIT NOAA TWG Meeting May 12, 2011 Sutron Corporation 22400 Davis Drive, Sterling VA 20164 Tel: (703) 406-2800 Email: tempest@sutron.com

  2. Not your Grandfather’s LRGS TWG 11/17/2010

  3. DCS Data Flow TWG May 12, 2011

  4. LRIT Availableon both GOES East & West • Combined data stream of ALL DCPs is sent to both GOES east and west . • LRIT from either Satellite gets the entire DCS TWG May 12, 2011

  5. LRIT sends Files • LRIT is a File Transfer mechanism. • Not efficient to send each DCP Msg in a Separate File • Files are sent as High, Medium, & Low Priority TWG May 12, 2011

  6. LRIT File Priorities • Each DCP Msg assigned a priority and placed in High/Medium/Low Priority File • Based on: Channel, DCP Address, Network List • NOAA sets 3 “limits” that control when files are closed-off and sent. • Max number of messages • Max time-span in seconds • Max file size TWG May 12, 2011

  7. We Recommend … • Limits Controlling when File is Sent: • How to assign DCP messages to priority: • High: A few very special DCPs (e.g. Tsunami) • Medium: Random channels • Low: Everything else TWG May 12, 2011

  8. Impact to Processing Software • LRGS with LRIT looks the same to downstream applications like DECODES. • No changes required! TWG May 12, 2011

  9. LRIT Receivers • We have successfully tested Tempest DAS (LRGS) with four different LRIT Receiver Vendors: • Dartcom, NVG, VCS, Avtec • The vendor provides software for file reconstruction, image capture, and processing. • LRGS processes DCS files and serves them out to clients like DECODES. TWG May 12, 2011

  10. Sutron LRIT Receiver • Components are Similar to DOMSAT: • Small dish, LNB, Receiver, PC, Software TWG 11/17/2010

  11. LRIT ProvidesDCS Data and GOES Imagery • Visual & IR Images • Can be saved to TIFF, JPG, PNG • Automatic collection, zoom, geo-reference grid • Animations • Easy integration to web site • DCS Data • LRGS ingests data from LRIT and merges with other data sources you might have (DRGS, NOAAPORT, DOMSAT, DDS, etc.) TWG 11/17/2010

  12. Sutron LRIT Software with LRGS TWG 11/17/2010

  13. GOES Imagery Data TWG 11/17/2010

  14. Compare DOMSAT & LRIT TWG May 12, 2011

  15. DOMSAT Footprint TWG May 12, 2011

  16. Impact to Current DOMSAT Users • Need to purchase: • Dish, LNB, Cable, • LRIT Receiver (We resell Dartcom), • Decommutation & Image Processing Software • PC (may be required, Dartcom requires Windows) • Current Tempest LRGS Users: • No additional license costs • We will assist you to upgrade & re-configure TWG May 12, 2011
