1 Introduction
1.1 The Digital Satellite System
Your new TracVision 4 satellite antenna is fully compatible with
the Digital Video Broadcasting (DVB) satellites, which use the
international standard for digital TV transmissions, and with the
DIRECTV
®
DSS satellites. As a result, you will be able to receive
and decode signals from either DIRECTV, The DISH
™
Network,
or ExpressVu with the proper programming and hardware (e.g.,
the Integrated Receiver Decoder [IRD] for your selected service).
TracVision 4’s default satellite setting is to acquire, track, and
receive signals from DIRECTV’s DSS 101 satellite. However,
TracVision 4’s software is preprogrammed with the satellite
locations and transponder information for the following North
American satellites:
• DSS 101˚ W • DSS 110˚ W*
• DSS 119˚ W • EchoStar 61˚ W
• EchoStar 110˚ W • EchoStar 118˚ W
• EchoStar 119˚ W • EchoStar 148˚ W
• ExpressVu
* Contact KVH or DIRECTV for complete details on tracking and
receiving signals from DSS 110.
1.2 TracVision 4 System Overview
Your KVH TracVision 4 employs 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 transmits commands to the antenna motors to
keep the antenna pointed at the satellite at all times. This active
stabilization is enhanced by a conical scan tracking function to
detect and lock onto the strongest signal, resulting in the clearest
reception possible. System specifications have been provided in
Appendix A.
