Description:
A real-time tomography system has been developed which combines ocean acoustic tomography with satellite-based time keeping
and satellite telemetry. The basis of the system is the acoustic tomography transceiver and its associated acoustic navigation grid.
To this basic system, a link to the surface has been added to provide a pathway for telemetry of the tomographic data to shore and a downlink for satellite-derived time which is used to correct the transceiver's clock. The surface buoy contains a GPS receiver, clock comparator, system controller and multiple ID Argos transmitters. Processed tomography signals, transceiver location data time, time drift and surface buoy engineering data are transmitted to satellite using a total of 32 data buffers transmitted every eight minutes. The report describes the real-time tomography system in detail, with particular emphasis on the modifications
implemented to convert the standard tomography instrument to a real-time oceanographic tool.
