TracVision G4 is the first marine satellite television antenna system designed to track and receive signals from a range of Digital Video Broadcasting (DVB) satellites. The TracVision G4 features a built-in DVB-compatible tuner and an easy-to-use interface that makes older marine satellite systems obsolete. Boats can now track service, including the DISH network and Expressvu, and receive high-quality digital TV, data and music. The TracVision G4 includes KVH's GyroTrac sensor, which provides earth-referenced heading data for faster satellite acquisition. KVH Industries, Middletown, RI; (401) 847-3327; www.kvh.com.
