Acoustic Oceanographic Buoy (AOB)

The AOB is an integrated system composed of a piece of hardware to be deployed at sea (from a surface ship or aircraft) and a software utility that interfaces with the user at a remote location on real time. The AO-Buoy capabilities are as follows:

• easy to handle system tending to the size, weight and autonomy of a standard sonobuoy
• several depth modulable wideband acoustic and non-acoustic (thermistors, depth sensors, ...) channels
• on the buoy GPS for time and location reference
• on the buoy pre-processing for data reduction and analysis
• fast remote wireless communications for data online monitoring and processing
• online tracking of AO-Buoy position, status and data being acquired
• real time data processing with the following scopes: water column temperature profiling via tomographic inversion, geo-acoustic bottom inversion, sound source detection, localization and tracking and underwater communications in the band up to 16 kHz.
