ProSAS-60
The PS60 system combines Applied Signal Technology's extensive SAS algorithm development and sonar design with Williamson's vast experience with deep ocean search and survey. Surface components of the system consist of AST's proprietary PROSAS software and hardware suite and an SL Hydrospheric Surface Telemetry unit while the subsurface components feature AST's 6000m housed electronics with a Kearfott T18 Inertial Navigation System, two 3-meter arrays, two projectors, an SL Hydrospheric Subsurface Power/Telemetry unit and a Teledyne RDI DVL. The subsurface components are integrated onto a 6-meter-long towfish which is de-coupled from the towing vessel by a 50 meter umbilical and a 2000 lb. depressor weight. Topside processing consists of a commercial processor with four displays that allow users to view real-time port and starboard SAS waterfalls, bathymetry, multibeam sidescan, and to view and save contacts and regions of interest for further detailed analysis. An IXSEA Posidonia USBL is used for precise positioning of the towed vehicle at all times. The system provides a new level of deep, long-range, high-resolution imagery that is ideal for wreck searches, cable route survey, pipeline route survey, and a wide variety of other deep ocean imaging requirements.
