SEMI-AUTONOMOUS MAPPING SYSTEM (SAMS) 
NAVOCEANO is also pursuing small UUV technologies in the form of a modified Woods Hole 
Oceanographic Institution REMUS vehicle, identified as Semi-Autonomous Mapping System 
SAMS leverages existing Towed Oceanographic Survey System (TOSS) Relative 
Acoustic Tracking System (RATS) to achieve precise acoustic positioning.

and post-mission ascent. 
The capability improvements and benefits to be realized with SAMS include: 
Extended capability of existing TOSS full-ocean depth camera and side-scan 
sled 
Increased rate of survey coverage, reduced ship time, and/or significantly 
increased survey coverage and data collection 
Progress on UUV Priority Ill to provide large-area oceanography and tactical 
oceanography support 
Greater positioning accuracy via internal navigation system 
Compatibility with existing ship stowage, deployment, and retrieval systems 
14-hour autonomous survey time 
Uninterrupted survey with continuous two AUV rotation operational plan
