In-motion Tracking (TracVision L3 only)
The TracVision L3 employs a state-of-the-art actively stabilized
antenna system. Once the satellite is acquired, the antenna gyro
continuously measures your vehicle’s motion and position, and
transmits commands to the antenna motors to keep the antenna
pointed at the satellite at all times.
1.2.1 TracVision L3/S3 Components
The antenna unit includes the antenna positioning mechanism,
signal front end, power supply, and control elements. The
antenna is a parabolic dish mounting a low noise block (LNB)
converter with built-in preamplifier. The European configuration
includes a single-output LNB while the North American system
uses a dual-output LNB. A molded ABS radome encloses the
fiberglass baseplate and is secured in place with standard
fasteners. Connectors on the back of the baseplate join the power,
signal, and control cabling from units inside the vehicle.
1.2.2 Integrated Receiver Decoder (IRD)
The IRD (purchased separately) receives satellite signals from the
antenna unit for signal processing and channel selection, and
sends the signals to the TV set for viewing. The IRD also
provides the interface for the user to activate authorization for
reception. Please refer to the User’s Manual provided with your
selected IRD for complete operating instructions.

Introduction
54-0157 Rev. G
The dual-output LNB in the North
American systems allows two
IRD/TV pairs to be connected
directly to the antenna. Three or
more pairs can be connected to the
system if an active multiswitch is
used. Section 2.3.5, “Connecting
the Antenna RF Signal Cable to the
IRD,” provides installation directions
for each of these options.
Before you can start watching
satellite TV using your TracVision
antenna, you will need to activate
your IRD. Refer to Section 2.4,
“Activating the IRD,” for more
details.
KVH offers an upgrade kit (KVH
Part #02-1026) that adds in-motion
tracking capability to the
TracVision S3, allowing you to
receive satellite signals while on
the move.
