1.1 TracVision 4 System Overview
A complete satellite TV system, illustrated in Figure 1-1, includes
the TracVision 4 antenna connected to the switchplate, an IRD
(satellite TV receiver), and a television set. The optional TV/SAT
Switch allows you to select a satellite at the press of a button. A
desktop or laptop computer is used to configure the system and
conduct diagnostics.
System Compatibility
The TracVision 4 satellite antenna is fully compatible with Digital
Video Broadcasting (DVB
® ) satellites, as well as DIRECTV ® ‘s
Digital Satellite Service (DSS) satellites. The system is also fully
compatible with KVH’s TracNet
™ 2.0 Mobile High-speed Internet
System (for more information about TracNet 2.0, please visit our
web site at
www.kvh.com ).
In-motion Tracking
The TracVision 4 uses a state-of-the-art actively stabilized antenna
system. Once the satellite is acquired, the antenna gyro
continuously measures the heading, pitch, and roll of your vessel
and sends commands to the antenna motors to keep the antenna
pointed at the satellite at all times.
