[email protected] www.sonardyne.com Datasheet AvTrak 2 (Omni-Directional Version) Description AvTrak 2 is a second generation 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 device that has been designed to meet the requirements of a wide variety of AUV mission scenarios and vehicle types. This capability can be used to provide absolute position reference data to periodically update the AUV’s inertial navigation system. The unit operates in Sonardyne’s Wideband® or HPR 400 Series tone modes with a variety of other systems and transponders. It is also fully compatible with Sonardyne’s family of survey quality LBL and USBL navigation systems. The instrument is available in a variety of configurations including depth ratings to 7,000 metres and a screened chassis option for mounting within the AUV’s own pressure vessel. The Type 8065 is a omnidirectional unit with integral or remote transducers. This flexible configuration is intended both to assist the AUV manufacturer with mounting of the instrument with the AUV and to ensure the highest levels of acoustic performance. A directional AvTrak 2 is also available (see Type 8140 datasheet). 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. An internal ‘watchdog’ feature monitors AUV comms activity and can switch the unit into transponder mode for emergency relocation. This feature is supported by an internal back up battery that provides power should the main AUV power fail. A number of acoustically controlled digital I/O lines are also provided for mission abort and emergency ballast jettison control.
