1 System Overview
A complete satellite TV system, illustrated in Figure 1, includes
the TracVision G8 antenna unit connected to the Master Control
Unit (MCU), an IRD (satellite TV receiver), and a television set.
System Compatibility
The TracVision G8 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 G8 uses a state-of-the-art actively stabilized
antenna system. The antenna’s built-in global positioning system
(GPS) allows the system to calculate the precise azimuth and
elevation to the satellite from your vessel’s current location,
ensuring the shortest possible satellite acquisition time. Once the
satellite is acquired, the antenna gyros continuously measure the
heading, pitch, and roll of your vessel and send commands to the
antenna motors to keep the antenna pointed at the satellite at all
times.
