1.1 System Overview
A complete satellite TV system, illustrated in Figure 1-1, includes
the TracVision G8 antenna unit connected to the Master Control
Unit (MCU), an IRD (satellite TV receiver), and a television set. A
desktop or laptop computer is used to conduct diagnostics.
System specifications are provided in
Appendix A on page 127 .
System Compatibility
The TracVision G8 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 KVH’s 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 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.
