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
• SUIRGs 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

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