SUIRG
Greetings and
welcome to the inaugural issue of SUIRG's eNewsletter. We will periodically
be providing news and updates about our organization as a service to our
members and also to spread the word about our mission and accomplishments
to the industry as a whole.
For those who
may not be familiar with us, SUIRG is the Satellite Users Interference Reduction
Group. Our primary goal is to reduce the number and length of satellite RF
interference incidents. We would like to eliminate incidents but in reality
all we can do is manage the problem.
Started informally
nearly 15 years ago by concerned members of the satellite operator community,
SUIRG incorporated in 2002. Our membership has since expanded to include
a range of satellite operators, users, interference identification and location
equipment manufacturers, and many related satellite organizations or service
providers.
In this premier
issue of SUIRG eNews, you will hear what SUIRG has been doing to classify
and manage the RFI problem from our Chairman, James Budden. We also highlight
a good news story from one of our members, PanAmSat, in the battle against
RFI.
Before I sign
off, I would like to extend an invitation to attend SUIRG's 2006 Annual Conference
and Meeting, which will be held July 11 thru 13 in Stockholm, Sweden. We
will waive the registration fee for first time attendees to encourage you
to learn for yourself the benefits of SUIRG membership and networking. For
more information, click here: http://www.suirg.org/events.shtml. We hope
to see you in Stockholm!

Satellite Communications Operations Consulting
The Satellite Users Interference Group
Inc. (SUIRG) has been engaged in efforts to reduce radio interference to
geostationary satellite capacity since the Group's inception over a decade
ago. A key SUIRG activity has been the collection and analysis of data on
global interference events for analysis. Early results of this data collection
campaign have driven SUIRG to concentrate its efforts on three specific remedies
that could have a major impact on the number of interference events.
First, in cooperation with WBU-ISOG
and others, SUIRG produced globally recognized VSAT and SNG Universal Access
Procedures. All SUIRG member satellite operators have agreed to abide by
these procedures as best practices and minimum performance requirements for
mobile operators. it's the Universal Access Procedure were presented to the
ITU last year, who endorsed and accepted the communications carrier satellite
up-linking guidelines as an ITU standard.
Secondly, in collaboration with WBU-ISOG
and GVF, SUIRG produced VSAT installer guidelines to ensure a global common
minimum standard for installers. These training guidelines incorporate all
requirements for an installer to complete a professional installation. SUIRG
and GVF are now surveying VSAT installation training programs with the goal
of updating those with deficiencies and approving those which meet the SUIRG/WBU-ISOG/GVF
standard.
SUIRG'S' third remedy, a longer-term
effort, is to introduce an Interference Source Identifier (ISI) on all digital
carriers. This enormous task kicked off with the definition of minimum data
that should be embedded in a carrier to identify its source.
As a starting point, SUIRG and two
of its member vendors are investigating the requirements for SNG video carrier
ID since these are the most active carriers on any satellite system. The
carrier ID will be used to assist in the identification of an interfering
carrier by cross-referencing the ID with the equipment owner. Discussion
is centered on where to embed the data, at the encoder or at the modem, how
much data can be embedded in the overhead channel, and what data is required
and what is optional. Also under consideration are the database requirements
where the ISI equipment code and owner are cross-connected.
In addition to the goal of reducing
RFI, an additional challenge is to make ISI a firmware upgrade that is backward
compatible to units already in the market. It must also be inexpensive and
as simple to implement on installed equipment as it is on the manufacturing
line.
Satellite operators will require a
communications monitoring system to extract this ISI data from the digital
stream, while the monitor vendors will need to have the adaptive firmware
in place to achieve the desired result. The Digital Spectrum Analyzers currently
on the market are short-term capture and do not hold sufficient data to extract
the ID from the incoming stream. However, the forthcoming third generation
units will be able to sample sufficient time in the data stream to extract
the required ISI data and present it to the monitoring operations center.
The final piece of the Carrier ID
puzzle is for SUIRG to capture and track manufacturers' data that is embedded
in the stream available to all satellite operators. This will involve close
and careful coordination to overcome proprietary sales and customer data
issues.
SUIRG and its members are actively
engaged in and pursuing these RFI prevention remedies. We are optimistic
of making good headway and to reporting positive progress report at our July
annual meeting in Stockholm (http://www.suirg.org/events.shtml) as well as
through this newsletter.
SUIRG Member PanAmSat Honors 77 With Operational
Excellence Awards
In its ongoing effort to promote and acknowledge error-free
operations at all uplink sites that access its satellite capacity, PanAmSat
honored 74 broadcasters with its Operational Excellence Award in 2005. Many
of the award recipients were not even direct customers of PanAmSat, further
reinforcing the aims and objectives of the awards program.
Minimizing RFI (Radio Frequency Interference) continues
to be one of the hottest topics at PAS user group sessions. In addition to
training programs and industry wide access standardization, a recommendation
from these User Groups was for PanAmSat to expand its award and incentives
programs to further increase the awareness within the satellite services
user community. Consequently, the Company modified its annual Operational
Excellence Award program to focus on the broadcast user group.
In addition to overall winners in broadcast, full-time
video and data, PAS designed a tiered level of award winners, including Platinum,
Gold, Silver and Bronze level winners. Awards depend on the number of error-free
accesses by each user. In 2005, PAS required a minimum of 50 accesses to
be considered for an award. Click
