  1. SDI-104 Status Dave Santek SDI-104 Program Manager 2 June 2009

  2. Overview • SDI Design • Hardware configuration • Software configuration • Satellites signals and SDI-104 availability

  3. Hardware Configuration • PC/104-Plus • 1 GHz CPU • Boot from compact flash • Ethernet: 10/100/1000 BaseT • Connectors for monitor and keyboard • Mounted in 2U rack box

  4. Hardware Configuration Data rates up to 30 Mbits/s • Connectors: • D15P • BNC • Configuration: • Single ended (TTL) • RS422 (differential) • Data types • NRZ-L, NRZ-M, NRZ-S • Jumper configurable

  5. Software Configuration • Linux • Ingestor software modified slightly from previous SDI systems • ADDE server software is unchanged • Can be configured as a standalone ingestor/server, or to write data to an external disk (via NFS, for example)

  6. Event Notification • Notifications are dependent on signal type: • Image start (not for POES) • Image end (not for GVAR Imager) • Three types of notifications: • Send an email • Write notification to a file (log messages) • Run a program or script

  7. SDI-104 Status for Current Satellites • GOES: no change; adapting servers for the final two GVAR satellites • MTSAT: • HiRID format: no longer available • HRIT format: modifications for rapid scan • POES Relay • Current through NOAA-19 • Unable to test direct reception

  8. SDI-104 Status for Current Satellites • FY-2C: Chinese geostationary • Ingestor in use in Japan • MSG: not available, although we are investigating hardware and software needed to receive • Metop • Current satellite does not have direct broadcast • SSEC does not have a direct readout station, but we may in the future

  9. SDI-104 Status for Current Satellites • Meteosat-5 and –7: not available • DMSP: not available

  10. Future Polar Satellites We are monitoring the status and data delivery of future polar orbiting satellites NOAA-N’, NPP, and NPOESS. We expect these to have a Direct Broadcast mode and are investigating having SDI-104s available.

  11. Future Geostationary Satellites We are monitoring the status and data delivery of GOES-R. We expect it will use an industry-standard delivery (such as CCSDS), which the SDI-104 can ingest. Also, the SDI-104 handles data rates up to 30 Mbits/s.
