Persistent Anchorless Active Sonar Craft (PAASC) Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-096 Topic Title: Persistent Anchorless Active Sonar Craft (PAASC) Proposal No.: N121-096-1351 Firm: Liquid Robotics, Inc. 1329 Moffett Park Dr. Sunnyvale, California 94089 Contact: Roger Hine Phone: (408) 636-4200 Web Site: www.liquidr.com Abstract: The Liquid Robotics Team proposed to adapt LRI's wave-based propulsion technology and AD&D, Inc. and Ultra USSI's DWADS sonar technologies to create a Persistent Anchorless Active Sonar Craft. Using a combination of conventional fossil fuel and wave-based propulsion, the PAASC will be capable of holding station in the presence of 1+kt depth-averaged currents for greater than 14 days. The PAACS's sonar system will include a transmit and receive array cable that can be deployed from depths of 75 to 500 ft. Benefits: The PAASC can be reconfigured for a wide variety of commercial and science mission payloads and applications, including long-term support of other unmanned maritime vehicles. Return
