KVH Industries TracVision L2 - Manual (Page 12)

1 Introduction
1.1 Digital Satellite Television
DIRECTV ® , DISH Network ™ , and ExpressVu 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 L2 automatically identifies, locks
onto, and tracks signals from the appropriate satellite, both while
your vehicle is at rest and in motion.
1.2 TracVision L2 System Overview
A complete satellite TV system includes the TracVision L2
connected to an integrated receiver/decoder (IRD) and a
television set. A desktop or laptop computer is used to conduct
diagnostics. The complete system is illustrated in Figure 1-1.
