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 SA automatically identifies, locks
on to and receives signals from the appropriate satellite when
your vehicle is stationary.

TracVision SA System Overview
A complete satellite TV system includes the TracVision SA
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 1-1. System specifications and a
functional block diagram are provided in
Appendices A and B
,
respectively.

TracVision SA System
Configuration
TracVision SA is equipped with a
single-port Low Noise Block (LNB)
that can provide signals to a single
IRD. Should you wish to equip your
vehicle with multiple TVs and IRDs,
a dual-port LNB is available as an
option (KVH Part Number 19-0056).
TracVision SA is a self-acquiring
satellite TV antenna for use when
your vehicle is stationary. The
system is not designed to track the
TV satellite when the vehicle is
moving.
