Vehicle Positioning - AvTrak

VEHICLE POSITIONING – AVTRAK

AvTrak 6 is an acoustic navigation and communications instrument designed to form part of an integrated AUV navigation system. It combines the functions of transponder, transceiver and telemetry link in one low power unit that has been designed to meet the requirements of a wide variety of AUV mission scenarios and vehicle types.

The unit operates in Sonardyne’s Wideband®2 or HPR400 Series tone modes making it compatible with a variety of other acoustic systems and transponders. It is also fully compatible with Sonardyne’s LBL and USBL navigation systems.

AvTrak has a comprehensive yet easy to use command language that allows the AUV to undertake simultaneous LBL ranging, USBL tracking via a surface vessel and robust telemetry for AUV to vessel and AUV to AUV communications.
