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), a satellite TV receiver (integrated receiver/decoder,
or IRD), and a television set. While all basic programming and
first-level diagnostic functions are available through the MCU, a
laptop computer can be used to conduct advanced diagnostics.
System specifications are provided in Appendix A on page 123.

Satellite 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.
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.
