What is the accuracy of underwater acoustics for auv velocity measurement?

1. 1* Working water depth: not less than 6000m.

1.2 ranging accuracy: 0. 15m.

1.3 working distance: 8km.

Deck tracking requirements of 1.4*: Using the ultra-short baseline carried by Science, the surface AUV can be upgraded and tracked, and the long baseline array can be calibrated accurately; Or the deck positioning unit can track the AUV surface and accurately calibrate the long baseline array without fixed installation.

1.5*AUV terminal positioning requirements: the positioning unit loaded by AUV can realize real-time accurate long baseline positioning of AUV and provide acoustic signals for water surface tracking.
