Chapter 1 - Introduction
System Components
The TracPhone V7 system includes the following components:
The antenna unit provides the satellite link
between the onboard modem and the land-
based hub. Using its integrated GPS,
advanced reflector technology, and gyro
stabilization, the antenna automatically
locates and tracks the correct satellite, even
while your vessel is on the move. In
addition, the antenna's three-axis range of
motion allows it to track the satellite at high
elevations, even directly overhead (requires
external NMEA 0183 true heading input).
The control unit links the antenna to the
modem and allows you to operate and
configure all aspects of the system.
The modem, manufactured by ViaSat, is the
transceiver and "brain" of the system. It
processes all incoming and outgoing TCP/
IP data between the antenna and the switch
using its proprietary spread spectrum
technologies.
The multimedia terminal adapter (MTA) is
a Voice over IP (VoIP) device that allows
you to connect up to two analog telephones
and make and receive calls over the mini-
VSAT Broadband connection.
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,
such as a wireless access point.
The remote service and support module is a
compact GPRS cellular modem that allows
KVH Technical Support to "dial in" to your
system for troubleshooting purposes.
