DATA ACQUISITION AND PROCESSING SYSTEM 



The shipboard data system known as the Bathymetric 

 Swath Survey System (BSSS) acquires data from a multibeam shallow 

 water sonar subsystem interfaced to a PDP 11/34 data acquisition 

 system (DAS) . The PDP 11/34 DAS system acquires sonar and navigational 

 data; corrects depths; provides navigational control; and 

 plots a contour strip chart, trackline, and swath coverage limits.
