Solution Benefits
• Cost efficient, high performance networks
The system is specifically engineered for installation on all
types of seagoing vessels, including offshore platforms, FPSOs,
semi-submersibles, survey and seismic vessels, as well as
tankers, passenger ferries and cruise liners.
• Easy expansion of service offerings to maritime customers
• High performance connectivity for data and multimedia
applications
• Highly efficient adaptive modulation and coding ensure the
High performance VSAT
Gilat’s SkyEdge and SkyEdge II VSAT platforms offer highperformance, cost effective delivery of a wide variety of
communications services, from interactive data to Broadband
IP, VoIP and beyond. Gilat has combined best of breed features
best utilization of satellite bandwidth
• High system reliability (high MTBF) and redundancy schemes
for all hub components
• Automatic acquisition of appropriate satellite signals from
into a high-performance platform.
mobile platforms ensuring that the VSAT/antenna are locked
The SkyEdge II family provides superior bandwidth efficiency
to the correct carrier
and high availability through the use of DVB-S2 ACM
(Adaptive Modulation and Coding) for the outbound paths.
• Secure transmission facilities
Supporting QPSK/8PSK/16APSK/32APSK modulation and
• Guaranteed pointing accuracy
LDPC coding provides superior bandwidth efficiency.
• Custom engineered antenna solutions for each client
and DVB-RCS based turbo coding. ICM provides 3 dimensions
of inbound adaptively: adaptive uplink power control, coding
and modulation and adaptive channels. These combine to
ensure high availability even in difficult maritime conditions
with a maximum dynamic range of up to 23dB.
