Advantages of ESVs
• Convenient, reliable and cost
effective communications
services.
• Combines voice, data, fax,
internet
• High speed data transmission
• Real time data exchanges
• Full-motion video applications
• Works in the harshest of
environments
2
How We Do It . . .
• Stabilized Antenna Platform on Ships
(multiple configurations)
• Commercial FSS satellites (both C-Band and
Ku-Band) to provide service (including
PanAmSat, Intelsat, New Skies, SES
Americom)
• Network based on IP, including VoIP
• Broadband broadcast to ships with
bandwidth on demand for return channel
• Single point of control at 24x7 network
operating center in Miramar, Florida.

Technical Advances in ESVs
• Pointing accuracy better than 0.2
degrees and tracking very stable
even in extremely rough seas
• Automatic control and location
improved
• Power and bandwith requirements
reduced through use of IP network
• Ku-band systems deployed for
inland waterways
• Dual-band systems still not
practical
4
Sharing with Existing Users
• Compatible with existing FSS satellite
networks
• Does not interfere with other FSS
stations
• Negligible increase in the number of
FSS stations
• Can use conventional frequency
coordination methodology when at a
predefined location
• In-motion frequency clearance
methodology developed through ITU-R

FCC Report & Order
• The FCC adopted regulations for the operation of
earth stations on vessels (ESVs) in a report and order
released Jan. 6, 2005 (Procedures to Govern the Use
of Satellite Earth Stations on Board Vessels in the
5925-6425 MHz/3700-4200 MHz Bands and 14.0-14.5
GHz/11.7-12.2 GHz Bands, IB Docket 02-10).
• In general, these new regulations are favorable to
the continued operation of ESVs and the growth of
the industry.
• In particular they provide a clear and certain path for
obtaining co-primary, permanent licenses for ESV
operation within the U.S.

FCC Report & Order
Main Licensing Requirements
• Network Control Facility
• Ship Location Tracking
• Antenna System Compliance
• Frequency Coordination

ITU-R Activity
• WP 4A: Updates to Rec. S.1587 –
Characteristics of ESVs with
specifications for smaller antenna
sizes
• WP 4-9S: Updates to Rec. SF.1649
with new detailed procedures for the
assessment of interference potential.

ETSI WG MAR ESV
ETSI has prepared candidate Harmonised Standards
for Ku-band & C-Band ESVs.
present status…
• Harmonised Standard EN 302 340,
requirements for protection of FS & FSS in Ku-band.
draft completed – March 2005
public enquiry – May-September 2005
• Harmonised Standard EN 301 843 part 6 (with TC ERM)
requirements for EMC in maritime environment for ESVs.
draft completed – March 2005
public enquiry – May-September 2005
• Harmonised Standard EN 301 447
requirements for protection of FS & FSS in C-band.
expected completion of draft – September 2005

CEPT/ECC WGRA
•WGRA has prepared two Decisions, one for Ku-band
and the other for C-Band ESVs.
•Both Decisions were adopted in May 2005 and will
be sent to the ECC meeting in June for approval.
•These Decisions allow for free circulation of ESV
terminals within CEPT countries if they have a
recognized license and comply with the ETSI
standards.
