The AUVs will act as a delivery system allowing for multiple subsea operations to take place depending on data collection requirements. Data will be sent through the water column acoustically to the USV during missions using the acoustic positioning (USBL) HiPAP 502. The USV will transmit data/communicate back to the HSV using the Kongsberg Marine Broadband Radio (MBR). This allows for real time monitoring of data while surveying to prevent holidays and/or monitor with still images. Communication back down to the AUV can also take place for minor mission plan changes such as direction and location.
