NSMA 2006 Meeting

SUIRG's mission is to address the growing problem of satellite interference and its economic impact. This update highlights ongoing activities, such as the Interference Location Identifier and membership growth. SUIRG also focuses on interference tracking, databases, and certification programs. State-of-the-art digital solutions for monitoring satellite communications systems are discussed, along with the benefits of the Interference Source Identifier program. The upcoming 2006 SUIRG Interference Conference in Stockholm, Sweden is also mentioned.

  1. NSMA 2006 Meeting May 2006

  2. MISSION SUIRG is dedicated to identifying and mitigating the growing problem of satellite interference and the economic harm it inflicts on the industry.

  3. Agenda • SUIRG Update • On-going Activities • Interference Location Identifier • SUIRG’s Future

  4. SUIRG Update • Membership grown to 35 members • 18 Satellite Operators • 9 Equipment /Tool Suppliers • 2 Non-profit Corporations • 6 Satellite User Associations

  5. On-going Activities • Up-linker Company Registry • Registration Process • Access Global Uplink Registry on home page “Uplinker Invitees” and complete form. • Request for registration will be forwarded to SUIRG office for approval. • To-date there are 96 Registrations

  6. On-going Activities • “Interference Matrix” Incident Logging Database • SUIRG Satellite Operators upload interference incident statistics quarterly • Oceanic Region • Interference Source • Uplink Region • Antenna Size • Antenna Size • Access to data available on Home page

  7. On-going Activities Interference Tracking- 6 months Interference Source Antenna Type Antenna Size

  8. SUIRG Update • Databases on SUIRG Inc. Web site. • Up-linker Company Registry • actively collecting up-link registrants • Interference Incident Logging • actively collecting interference incidents

  9. On-going Activities • Interference Source Identifier Program • Embed unique code in up-link transport data stream. • Monitoring system with capability of de-coding code out of data stream. • Cross-reference unique code with equipment owner/user. • Training & Certification Program • Working with various satellite operations training sources for SUIRG endorsement. • Development of SUIRG certification program.

  10. State of the Art Digital Solutions for Satellite Communications Systems Monitoring Using CSM Systems to detect Modem Unique Identifier

  11. Digitizers replace Spectrum Analyzers in CSM

  12. Detect Unique Identifier • Analyze Signal Characteristics • Determine modulation type and symbol rate • Determine Convolutional FEC • Determine Block Coding FEC • Hand Off to Receiver • Program receiver • Collect decoded data • CSM decodes data and determines Unique Identifier

  13. Determine Signal Characteristics • DSA can detect • Mod type • Symbol Rate • FEC • Even if Interference is sitting underneath a carrier

  14. Hand Off to Receiver • Use a modem as Receiver • Feed data stream back to CSM • Use CSM as Receiver • Limited capture range • DSA with Decimation give increased performance

  15. CSM Decodes Unique Identifier • CSM uses agreed standards to search for header containing unique identifier • New standards can easily be added by software upgrade • Mandatory backward compatible hard coded firmware info: • Equipment Manufacturer • Serial Number • Part Number • Firmware Revision Number • Optional firmware forward compatible info to be developed by committee

  16. Test Plan Outline • Insert code into modem • Start with QPSK and test various modulations • Send embedded code over satellite • Downlink to SAT, Inc. • Read code with CSM • Decode code via modem

  17. Schedule • Test plan • Draft plan by end July 2006 • Tests to commence in the Fall • Test results by end 2006 • System Specification • Draft by September 2006

  18. Interference Source Identifier Summary • Define code and implementation process • Investigate Video DVB-S2 physical layer framing standard which provides open header space to locate the unique ID code. • Working with vendors to develop test plan and system specifications for unique code identifier • SAT Inc. • Radyne/ComStream • Develop database to cross-reference unique ID with owner/manufacturer • Hosted on SUIRG Website

  19. Benefits • Multiple Benefits above Interference Source Identification • Verification of user & expected equipment prior to up linking feed • Pre-verification of equipment compatibility with other receiving equipment

  20. 2006 SUIRG Interference Conference/Meeting • 11-13 July 2006 • Stockholm, Sweden • Hosted by Swedish Space Corporation • Users Invited to attend complementary to explore membership

  21. SUIRG’s Future • To be proactive in interference reduction the driver for change must be the customer/user.  • Satellite operators and vendors can suggest process, system and educational changes; however, without the buy-in of the customer SUIRG’s ability to be proactive and mitigate interference is limited. • The customer or user of satellites must have some ownership of the process and actions taken. • If you support what SUIRG is doing then please consider membership.
