Introduction
1.1 Digital Satellite Television
The DIRECTV
®
and DISH
™
Network systems transmit digital
audio and video data from land-based transmitters to a
satellite “parked” above the equator. Each satellite relays the
signals in spot beams covering the continental United States
and contiguous waters. TracVision Cruiser is designed to
identify, lock on to, and track the appropriate satellite, both
while your vessel is at rest and in motion.
1.2 TracVision Cruiser
System Overview
Your KVH TracVision Cruiser employs a state-of-the-art
actively stabilized antenna system designed for use with
Ku Band satellite television reception. This vessel-referenced
stabilization system is enhanced by a conical scan tracking
function to detect and lock on to the strongest signal, resulting
in the clearest reception possible.
A complete satellite TV system includes the TracVision Cruiser
connected to an Integrated Receiver Decoder (IRD), aka a
“satellite receiver,” and a television set. A desktop or laptop
computer is used to conduct diagnostics. The interrelationship
of units is illustrated in Figure 1-2. System specifications and a
functional block diagram are provided in Appendices A and B,
respectively.
