1.1 TracVision G4 System Overview
A complete satellite TV system, illustrated in Figure 1-1, includes
the TracVision G4 antenna unit connected to the GyroTrac digital
gyro-stabilized sensor, Advanced Digital Control Unit (ADCU),
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 123.
System Compatibility
The TracVision G4 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 G4 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.
