Introducing I3
• Intelsat has made, and continues to make, capital investments
into tools and training to help troubleshoot and manage
instances of RFI on its network
• Intelsat understands that robust infrastructure is a needed first
step but that meaningful solutions require the entire industry
• Intelsat has embarked on the Intelsat Interference management
Initiative or, “I3”

Intelsat… Rallying the Industry
• I3 looks to leverage industry partners, including operators, industry
groups, customers and hardware manufacturers
• Satellite Operators Interference Working Group established in March
during Satellite 2009
– Intelsat teamed w/ SES and hosted the first meeting at Intelsat HQ in
Washington, DC
• Outreach to SUIRG, GVF and WBU-ISOG targeted initiatives
• Established the I3 Customer Advisory Team
– ABC Television – Vizada
– NHK – Gateway
– Global Crossing – MTN / Seamobile
– US Government
• Intelsat promoting I3 at industry events to inform customers and rally
support

Satellite Operators Interference Reduction
Working Group
• Formed March 2009
• 11 satellite operators have joined
• Four (4) meetings held to-date
• Cooperation beyond critical
operations events
– RFI investigation
– Management of Adjacent Satellite
Interference (ASI)
– Coordination of In Orbit Testing
– Satellite hinder coordination
• Operators have, in general, endorsed
common set of initiatives targeted to
reducing RFI consistent with the I3
program

Carrier Identification (ID)
• Goal: To provide the means to identify an interfering carrier to
minimize outage/degradation resolution time
• Variously referred to as ‘Carrier ID’, or in the United States ‘ATIS’
– Concepts for video (MPEG) carriers developed through WBU-ISOG and
SUIRG
– Capability demonstrated at WBU-ISOG in 2006
• Two basic forms of the capability
– Transmission of uplink GPS location and other ID info
– Transmission of ID info only (requires database cross-check)
• Information can be embedded in:
– Modem header information
– Incorporated into encoding standards
• Adoption by vendors/manufacturers is key to the success of this
approach

10. 5792-Business-Update - 10
Carrier Identification (ID)
• WBU-ISOG and SUIRG continue to promote this technology for
video carriers, industry has been slow to adopt
• Intelsat along with the members Satellite Operator Interference
Working Group have reviewed the WBU-ISOG proposal of June
2008
– Developed requirements/standards for Carrier-ID insertion and
extraction system for all other non-MPEG carriers
– Formal endorsement by all operators expected upon final review
– deadline 30 August 2009
• Implementation timelines to be determined in coordination with
industry partners
• While WBU-ISOG proposal covers only video carriers, Intelsat
is taking the lead to also promote the use of Carrier ID for data
carriers

Data Sharing and RFI Alert System
• Satellite operators use informal sharing of RFI event
information as a key tool in resolving RFI
– Information sharing is not structured nor archived
– Obvious commercial sensitivities have hampered progress
• In order to support proper investigation, operators need to
share more detailed information through an RFI Incident
Database
• Satellite Operator Working Group now discussing methods to
improve the cooperation on RFI resolution
– Investigating structured means of sharing and archiving event
information data
– SUIRG has in the past collated ‘anonymous’ interference data for
statistics
• Sharing of RFI Incident Data would most likely be achieved
through and in concert with a RFI Alert Network

12. 5792-Business-Update - 12
Data Sharing and RFI Alert System
• The exchange of operational data (Data Sharing) is key
to a number of critical satellite operations activities:
– Interference analysis including Adjacent Satellite Interference
(ASI)
• Requires transmission plans, beam coverage, antenna
performance
– RFI Geolocation
• Using interferometric techniques, requires ephemerides, adjacent
satellite configuration, Reference Emitters (known uplink
sources) with Lat./Long.
• Exchange has been informal between operators
• Recent efforts have sought to standardize, formalize
and automate processes

13. 5792-Business-Update - 13
Data Sharing and RFI Alert System
• Facilitate better collaboration between Satellite Operators handling
real time Radio Frequency Interference (RFI) events
– Reduce certain customer service impacting events
– Facilitate cooperation between operators for more “eyes in the sky”
• RFI Alert is an email based system
– Single address RFI ALERT distributes to all Satellite Operators
– Housed by SUIRG
• Once sent
– RFI Alerts will be reviewed by all operations centers in near real time
– Operators will “clear” their networks
– Alert originator sends “all clear” notice upon resolution
• Proof of concept completed in May 2009
• First system test completed in August 2009
• As of this meeting, system not yet used for real event

Training and Certification
• Intelsat has reviewed two programs and endorses both
• Intelsat has committed funds to train and certify customers in targeted
regions with major interference issues
• Intelsat making a 3-year commitment to train and certify those that
can’t afford training
• Focusing on customers with history of interference-causing behavior
• Teaming with other operators to keep costs down, spread the burden
and penetrate market
• Intelsat encourages all customers to:
– Train installation and teleport staff
– Use trained and certified integrators/installers

15. 5792-Business-Update - 15
Training and Certification
• GVF provides specific training for the installation and operation of
VSAT networks, which, as members of GVF, is endorsed by Intelsat
and SES:
– http://www.gvf.org
• A list of GVF certified installers can be found at:
– http://www.gvf.org/training/index.cfm?item=installers
• Training specific to mobile SNGs can be found at
Beaconseek/Slingpath:
– http://www.slingpath.com
• In addition to these training packages which are also relevant to fixed
earth stations, there are other reputable sources such as:
– Skjei Telecom: http://www.skjeitelecom.com
• WBU-ISOG & SUIRG provide criteria for recommended training
packages:
