Chapter 1 - Introduction
System Components
The SAILOR 700 VSAT system includes the following components:
The
ADU
provides the satellite link between the
onboard modem and the land-based hub. Using its
integrated GPS, advanced reflector technology, and
gyro stabilization, the ADU automatically locates and
tracks the correct satellite, even while your vessel is
on the move.
The
ACU
supplies power to the ADU, links the ADU
to the VMU, and allows you to operate and
configure all aspects of the system.
The
VMU
, manufactured by ViaSat, is the
transceiver and “brain” of the system. It processes
all incoming and outgoing TCP/IP data between
the ADU and the switch using its proprietary
spread spectrum technologies. It also powers the
ADU’s transmission and reception components,
Block-Up-Converter (BUC) and Low Noise Block
down-converter (LNB).
The
switch
links the system to your onboard local
area network (LAN) via wired Ethernet connections.
Four of its eight ports support Power over Ethernet
(PoE) - they can supply power to any IEEE 802.3af-
compliant device, including the Thrane IP Handset.
If you connect a wireless access point to the switch,
be sure to apply security settings (such as
encryption) to protect the network.
The
remote service and support module
is a
compact GPRS cellular modem. This unit allows
Technical Support to “dial in” to your system for
troubleshooting purposes.
