Sonardyne's multi-function acoustic instrument, AvTrak 6, is one of the most versatile sensors you can fit to an AUV. Use it for inertial aiding, long-range tracking, communicating, and mission planning and start improving the accuracy and value of AUV surveys or working on collaborative unmanned operations of unmanned systems.
AUVs use an Inertial Navigation System (INS), aided by a Doppler Velocity Log, to continuously work out their position. However, over time, the estimated position of the INS system "drifts" as small dead-reckoning errors accumulate. Providing acoustic position updates to the AUV can mitigate this effect-and that's where AvTrak excels.
Three models are now available, with the smallest OEM version roughly the same size as a business card, and the deepest being depth rated to 7,000 meters. All are...
