TRANSCRIPT
NSMA 2006 Meeting
May 2006
SUIRG is dedicated to identifying and mitigating the growing problem of satellite interference and the economic harm it inflicts on the industry.
MISSION
Agenda SUIRG Update On-going Activities
Interference Location Identifier SUIRG’s Future
Membership grown to 35 members 18 Satellite Operators 9 Equipment /Tool Suppliers 2 Non-profit Corporations 6 Satellite User Associations

SUIRG Update
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.

Digitizers replace Spectrum Analyzers in CSM
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
Determine Signal Characteristics
DSA can detect Mod type Symbol Rate FEC
Even if Interference is sitting underneath a carrier
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
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
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
Test Plan Outline
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
Schedule
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
Interference Source Identifier Summary
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
2006 SUIRG Interference Conference/Meeting 11-13 July 2006 Stockholm, Sweden Hosted by Swedish Space Corporation Users Invited to attend complementary to
explore membership
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.
