This side-view of the ATLAS autonomous underwater vehicle (AUV) shows the sonar mounted on the nose, the orange GPS/WiFi antenna and strobe light mounted on top, and the fins with propeller at the stern. The underwater modem uses the small black transducer underneath the AUV to transmit and receive acoustic messages between the AUV and support ship.
