are dealing with…

background on irg
The former Satellite Users Interference Reduction Group (SUIRG) was restructured in February 2011 and rebranded:

satellite Interference Reduction Group (IRG)

…focused on Technology Solutions!

It will actively pursue interference reduction by promoting:

Coordination with other industry organizations to address regulatory issues, and ensure adoption of Carrier ID

Investigation and development of new technologies and techniques

Assist in the development of best operational practices, training and certification programs for installers and users through the End User Initiative (EUI now part of IRG; was RFI-EUI)

Support & coordinate with GVF, WBU-ISOG, APSCC, SSPi, MilSatCom

Members total 32, including satellite operators and other organizations

More input needed, to get new ideas, grow participation, expand industry-wide implementation of interference mitigation initiatives.

…background on IRG

What is Interference?…

  • Sustainability of space – two main aspects:
    • Physical security (collision avoidance, debris mitigation)
    • Electro Magnetic Interference (EMI) / Radio Frequency Interference (RFI)
  • Satellites are a shared resource (space, satellite, transponder)
    • In-band RFI (RFI within the operating frequency range of the satellite)
    • Out-of-band (RFI from adjacent frequency bands from the satellite)
      • Much higher power (e.g. terrestrial/mobile services) can affect the adjacent very low power satellite signals
  • Frequency spectrum of a satellite transponder
  • Blue trace is the authorized user signals
  • Purple trace is authorized plus interference
  • Users must be:
  • On the right satellite
  • At the right frequency
  • At the right power

What is the cause of RFI?...

Greater number of satellites

Reduced orbital separation

Growth of small ground terminals

Low equipment cost; lower quality; lower margins

Poor installations and maintenance

Lack of operational training

Faulty equipment

Sometimes intentional, but rare

Satellite Interference!…Carrier ID


satellite Interference Reduction Group

are dealing with…


DVB CID Update…

The End of the Beginning!

DVB completed its work on CID February 28th 2013

ETSI published the standard 29th May 2013!

ETSI TS 103 129


…so where are we?

  • We have an ETSI Standard (May 2013) & NIT!
  • 70% of all supplied Modulators are DVB CID ready now!
  • 80% of all supplied Encoders are NIT CID ready now!
  • SDA CID Database in production (ready for June 2014)
  • Detection Systems available now!
  • Eutelsat, Intelsat & SES putting CID Systems in place now!
  • WBU-ISOG Resolutions created CID targets! (May 2013)
  • ASBU Action Plan requires CID (Oct 2013)
  • FCC require ALL SNG/Flyaway Broadcast Platforms to be DVB CID compliant by 1st June 2016
  • Start CID rollout – 1st January 2015!

So moving forward…

  • Based on these particular WBU-ISOG resolutions with the aim to start rollout by 2015:
    • By 1 January 2015: All new modulators purchased for video uplinking will contain CID meeting ETSI DVB-CID standard
    • To meet Resolution 1, all Uplinkers of SCPC and MCPC video and data, fixed and mobile, will include DVB-CID in all RFPs for new modulators
    • By 1 January 2018: All uplinkers shall use DVB-CID on their SCPC and MCPC video and data transmissions
  • Can we find out who has CID (NIT or DVB)?
  • Who is requiring it? (Commercial/Military)
  • What planning is being done?

How we can support…

  • Providing better information, how?
  • Workshops, Events, Sessions?

What is CID?

  • Carrier ID is a unique identification code embedded on a transmitted carrier
  • This will be decoded by Satellite Operators to identify the uplinker of an interfering carrier
  • No customer information (location or contacts) need be included with the CID (although it may be optionally included). So privacy is ensured for the customer
  • Initially for DVB OU/SNG, video, data. Not VSAT TDMA
  • Two formats:
    • CID-NIT (old spec, to be phased out, may be compatible with existing equipment, requires uplinker to program the NIT)
    • DVB-CID (new spec, robust in presence of overlapping interference, spread spectrum technology, minimal user action)

What are the benefits?

  • Considerable effort and time is required for Operators to identify and resolve interference
  • CID will help identify interfering carriers
  • Not a magic solution for RFI, but a positive step that will help
  • Benefits:
    • Rapidly identify interfering carriers
    • Enable faster action to resolve interference
    • Improved QoS for customers (especially those affected by RFI)

How does DVB-CID work?

CID is transported in a spread spectrum carrier below the noise floor, under the main carrier

CID can be decoded even in presence of overlapping interfering carriers

DVB-CID carrier is at typically 27dB below the level of the main carrier

Degradation of the main carrier is <0.28dB

DVB CID Summary…

DVB CID standard relies on spread spectrum technology in modems/ modulators to embed CID in satellite transmissions

  • Mandatory Information – Fixed by the equipment manufacturer
    • 64-bit DVB CID Global Unique Identifier: Derived from a 48 bit MAC address or a 48 bit Space Data Association (SDA) modulator identifier
    • CID Format: A revision code anticipating possible changes in the revision number and possible content of the fields in the Content ID table

Optional Information – Added by end user

Carried in the Content ID table:

Latitude and longitude

Telephone numbers (up to 3)

User defined data fields (up to 7)


Next Steps…

Implementation of standard by manufacturers

Requirement for CID by end users in all new purchases

Requirement for CID by satellite operators in all uplink transmissions

Finalize CID standard

Some already implemented

70% by end

of 2013

Complete by June 1, 2013

What will encourage end users to require it?

How best to encourage all to implement?

Target date: January 1, 2015

Completion of the CID standard is only the beginning…now the real work begins


CID (usingNIT) - the Olympics - the Process (Manual)…

  • Each Satellite Operator (e.g. Intelsat, SES & Eutelsat) ensures the NIT contains the…
    • Manufacturer’s Code
    • Carrier ID # (Serial No/MAC Address –12 Characters max)
    • Optional - Satellite Operator name and contact info in to the User Field

Geo Stationary satellite subjected to Interference

Sat Ops #1

Sat Ops #2

Sat Ops #n

E.g. Sat Ops #1 detects & reports an Interfering Carrier

Carrier ID extracted & examined (e.g. User Info = Sat Ops #2)…

Then manually, cooperation between Operators…

Sat Ops #2 contacted & provided with Carrier ID#...



Sat Ops #2, using the reported Carrier ID#, determines

Customer and contacts for corrective action!

Satellite coverage on earth surface

This ensures Customer Data stays secure with the responsible Satellite Operator!



  • sIRG objective:
    • To prove CID process, use CID for World Cup OU video, June 2014
  • Based on WBU-ISOG resolutions:
    • By 1 January 2015: All new modulators purchased for video uplinking will contain CID meeting ETSI DVB-CID standard
    • To meet Resolution 1, all uplinkers of SCPC and MCPC video and data, fixed and mobile, will include DVB-CID in all RFPs for new modulators
    • By 1 January 2018: All uplinkers shall use DVB-CID on their SCPC and MCPC video and data transmissions
    • By 1 January 2018: All use of CID-NIT shall be phased out by this date
    • By 1 January 2015: All Satellite Operators shall start the transition to use CID that meets CID-NIT or DVB-CID standards (phasing out CID-NIT by 1 Jan 2018)
  • Based on new FCC Part 25 Rule (Digital ATIS):
      • By 1 June 2016: All SNG video transmissions must use the DVB-CID (ETSI) standard

Latest WBU-ISOG Resolutions…

At the conclusion of the recent WBU-ISOG Forum (May 15-16, 2013) held at Fox Networks in Los Angeles, there was agreement to issue a resolution in support of the recently adopted Carrier ID standard issued by ETSI (European Telecommunications Standards Institute) – ETSI TS 103 129 v1.1.1 (2013 – 05).  With this positive step forward by the industry to identify satellite transmissions of video content and as a means to mitigate harmful satellite interference, WBU-ISOG supports the following resolutions:

Exclusions and their Definition

The requirements for transmission of Carrier ID do not apply to MSS

systems which automatically configure frequency, power level, polarization and transmit inhibit according to commands issued by a central control mechanism which is in the control of the satellite operator.

The ETSI (European Telecommunications Standards Institute) – ETSI TS 103 129 v1.1.1 (2013 – 05) standard does not address systems that use TDMA or other types of burst carriers, and as such, equipment or systems that use TDMA or burst carriers are excluded at present from these resolutions.


WBU-ISOG supports the requirement that, by no later than January

1, 2015, all new model modulators and codecs with integrated modulators purchased by end users for video uplinking contain a Carrier ID (CID) that meets the ETSI TS 103 129 standard issued May 29, 2013.

Based on Resolution #1 and with immediate effect, the WBU-ISOG supports the requirement that all uplinkers of SCPC and MCPC Video and Data, fixed and mobile systems shall include Carrier ID functionality in the required specifications of all current and future RFP’s (Request for Proposal) or RFQ’s (Request for Quote) issued to equipment manufacturers regarding the purchase of modulators and/or codecs with integrated modulators.

The WBU-ISOG supports the requirement that all satellite operators, by no later than January 1, 2015 start the transition to use Carrier ID that meets WBU-ISOG NIT or the ETSI standard for all SNG, DSNG and any other New Uplink transmission services.

The WBU-ISOG supports the requirement that all uplinkers by no later than January 1, 2018 shall ensure that Carrier ID is included for all their respective SCPC and MCPC Video and Data transmissions.

The WBU-ISOG supports the requirements that CID NIT shall be phased-out in preference to the ETSI standard by January 1, 2018.


Moving Forward with CID…

  • Simple ID, simple fix!
  • Operator-to-Operator Automation - SDA)
  • Use MAC Address only
  • Secure ID-to-Operator Link
  • Simple Trace: Carrier-to-Operator
  • Hold applicable Carrier Data details - Operator only!
  • Accuracy & Maintenance

Use both NIT (ideal start for SNG) & migrate to DVB Standard…


Satellite Operator Tasks

  • Develop CID ops processes
    • Key objective: minimize complexity and expense for users
    • Decode ID during line-up/ routine monitoring, enter in carrier dbase
  • Specify inter-Operator (e.g. via global dbase) processes
  • Develop global CID database (prototype June 2014, final in 2015)
  • Implement CID decoding in monitoring systems (basic functionality by June 2014, full functions for 2015)
    • Need rollout plan. Large Operators have dozens of mon sites to equip
  • Promote CID to customers (uplinkers)
    • Info to sales teams and customers, industry presentations
  • Implement CID at our own teleports (uplinks)
    • Target 2015-2018 depending on modem capability and refresh cycle
  • Longer term automation plans
    • Auto detection of CID and immediate checking of databases

CID Global Database

  • SDA will develop and host a global database for Operators to associate a CID with the name of the Satellite Operator who is transmitting the carrier with that code
  • Allows an Operator who is affected by interference to quickly find the name of the Satellite Operator to contact, to investigate and resolve the interference

are dealing with…


Types of RFI and taking a look at VSATs…

  • To put it in perspective:
    • The amount of capacity affected by RFI at any time, is very small compared to the total capacity
    • However, for an affected customer, it is harmful interference
  • Impact to industry:
    • Poor quality of service; affects revenue; bad perception of satellites
satellite interference difficult cases

Satellite Interference!…Difficult Cases


satellite Interference Reduction Group

are dealing with…


Deliberate Jamming…

Abu Dhabi MilSatCom Intro for reference…

“As satellite communication technology evolves and continuous to grow, satellite networks are increasingly subject to radio frequency interference from a variety of ground transmitters. In an interesting panel, regions SatCom users outline steps they undertake to eliminate interference and outlines measures they expect from operators, regulators and system providers that can help their efforts.”

Affects to the Broadcaster & Regulation…

Jamming – Cover both Intentional and typical instances of Interference

Mention Short Wave issues (BBC World Service/VoA) (Something the BBC reminded me of at CabSat!)

ITU Perspectives of where we are regarding harmful Interference, Geneva meeting 10th June where IRG/GVF helped present a day forum to National Entities on this subject.

Note, previous Meetings/Events with full IRG participation…

IRG Conference (Dubai) 18/19th November 2012

BBC World Service (London) 20th November 2012

Eutelsat (Paris) 18th January 2013

CabSat (Dubai) 12th March 2013

Satellite Show (DC) 21st March 2013

MilSatCom (Abu Dhabi) 8th May 2013

ITU (Geneva) 10th June 2013 (What happened?)


Jamming - continued…

Proactive Solutions/Prevention…

An Audience reminder on Training, Installation, Certification & Quality Assurance/Type Approval Update on what is now available for SNG, how does Training help prevent – GVF Initiatives…

Note, we can add as part of the discussion period about  RFI-EUIs role General Access Procedures and SNG Training, using this & other tools to help prevent interference in the first place, etc. etc.

Carrier ID…

Carrier ID DVB Standard - Bring us up-to-date with the DVB/ETSI, leading what really must be done to get CID implemented, require it, customers to specify it, etc. (see other parts of this presentation)


Jamming - continued…

  • Reactive Solution – Processes, Tools & Technology…
  • Interference & Geo-Location
  • Brief to intro Geolocation for the audience as the final approach when all other avenues have been exhausted…
  • New standards to be developed for Geolocation Data output (agreed at CabSat 2013 between SAT Corp, Siemens & Zodiac Aerospace) including ITU request to initialize development of a standard for all ITU submissions. ITU Template received by IRG, first draft Geolocation Output Data template in time for Geneva meeting, 10th June 2013; with a view to creating an ISO standard…
  • Thus improving evidence gathering!
  • Discussion on allowing more monitoring stations to submit Geolocation data, with that standard, to allow more evidence of any single threat for the ITU to put forward to any entity, national or otherwise, to ensure accurate, common format, independently registered sourced evidence to provide that compelling case!

Jamming - continued…

  • Reactive Solution – Processes, Tools & Technology (continued)…
  • Interference & Geo-Location
  • Predictive Geolocation, using the politics to govern where the most likely target services & put a “watch” on those services.
  • Suppression (more to come on this ready for Geneva & Communic Asia); smart receivers/filtering; Better Service/Frequency Planning Strategies…
  • Leading to issues raised at other events on Deliberate Jamming, Database for Difficult Interference Case Events – next 3 slides…

Database for Difficult Interference Case Events…

Creation of a database of all interference events – especially those caused Intentionally or by Piracy…

What Data would go into the Database?

Interference Received – satellite, transponder, start time, end time (when there is one)

Affected party – CID, geo-location of transmission, content, modulation parameters, company and contact

Interfering party – CID, geo-location of transmission, content (if any), modulation parameters (if any), company/contact (if known)

Spectrum details, Plots, Recordings, Log of Detection and Resolution Activity, etc.


Database for Difficult Interference Case Events…

Creation of a database of all interference events – especially those caused Intentionally or by Piracy…

So Questions that should be Answered are…

What use would the Data be put to? (e.g. Space Data Association SDA)

Who are the expected Contributors?

How possible is it to ensure that the Data was correct and that it was not being distorted by false information?

Would everyone be happy for their Data to be used for whatever purpose required by the users or administrators of the system (We understand that it would be against the rules to use it for commercial ends, but what about political situation?)


Database for Difficult Interference Case Events…

Creation of a database of all interference events – especially those caused Intentionally or by Piracy…

the Thinking...

This database would be populated and corroborated only by satellite operators.  The affected party, and possibly the interfering party, would provide details to the satellite operators so that the data entered by satellite operators are as accurate as possible.  The data would be used for trend analysis – content that is jammed, jammers, etc.  Offenders, along with collected evidence, could be turned over to the ITU, the UN, and the governments of the affected and interfering party to support political negotiations.

Anonymous (without company, contacts or specific geo-location) data might be made available to research teams, overseen by IRG/SDA, that can use the data to design filters and other methods that would render jamming attempts ineffective.

satellite interference space data association

Satellite Interference!…Space Data Association


satellite Interference Reduction Group

are dealing with…

what is the carrier id database
What is the Carrier ID Database?
  • Centralized database for all satellite operators to use, at no charge, to store/search for Carrier Unique IDs
  • The database will associate Carrier unique IDs with the satellite operator whose satellite is transmitting the carrier with that unique ID
  • Allows satellite operator who is affected by interference, to quickly find out who is responsible for the interfering carrier
  • User account administration by sIRG and/or SDA (to be decided)
  • The database will support the new DVB-CID specification, and the previous NIT CID encoding (which will eventually be phased out)
status of the cid database cidb
Status of the CID Database (CIDB)
  • SDA has approved hosting of the CIDB
  • High level requirements are drafted
  • Development of a prototype CIDB by AGI is in progress and will be first demonstrated to satellite operators and industry at the sIRG Conference in Brazil, 16-18 Oct 2013
  • Feedback on the prototype will lead to more detailed definition of the requirements for development of a production database
  • Target timeframe for readiness of a production CIDB is early-2014
  • The SDA has a requirements team overseeing RFI/CID functional development, and will work with sIRG CID WG
cidb top level functions 1 of 3
CIDB Top-Level Functions (1 of 3)
  • Centralized, global database, accessible by all satellite operators at no charge
  • Sufficient controls for user access and data security
  • User administrators will be authorized by sIRG/SDA (TBD), and user accounts will be controlled by operator company administrators
  • CIDB will support the new DVB-CID specification and former DVB-NIT format. (NIT usage to be phased out)
  • The data fields in the DVB-CID and NIT specs will be supported in the CIDB
  • CIDB will have user GUI and also web services access
cidb top level functions 2 of 3
CIDB Top-Level Functions (2 of 3)
  • Basic CIDB search functions:
    • Search for a CID unique identifier (meeting DVB-CID spec), and obtain satellite operator associated with that CID
    • If the CID appears on multiple satellites (e.g. an SNG service), all operators will be listed
    • Search for a NIT identifier (made up of equipment manufacturer and serial number, in accordance with DVB-NIT spec), and obtain satellite operator associated with that identifier
    • Search for a satellite operator and obtain contact details
    • Search for the name of a contact person and obtain the satellite operator associated with that name and contact details
cidb top level functions 3 of 3
CIDB Top-Level Functions (3 of 3)
  • Basic CIDB edit functions:
    • Satellite operators can edit their own contact information and create CID records associated with their company
    • CID records cannot be deleted. This will retain a history of a CID (modem)
    • Mandatory fields are Unique ID, and satellite operator. All other data fields are optional
    • An operator can create a CID record, even if that CID already exists for another operator. This may be applicable for modems that are used on multiple satellites, such as SNG services
    • Records will be date/time stamped
