MISSION 2012 objec9ves achieved USA " Operate 10-­‐node Seaweb wide-­‐area network in noisy, high-­‐current Singapore Strait " Exercise linear network with 8 hops and 556-­‐
byte data packets " Deploy data recording telesonar testbed as a surrogate interceptor " Record 24 hours of intensive network ac@vity for link margin and TRANSEC analysis " Perform network discovery and autonomous ini@aliza@on of network routes using cost func@on op@mized to favor r=500m links SIN " Operate 4-­‐node Unet local-­‐area network " Test Unet modem soaware " Evaluate ranging performance " Measure variability of communica@on channel " Observe in-­‐band ambient noise and its rela@onships to external factors (diurnal cycle, rain, wind, shipping, etc.) Seaweb

Project “NGAS” NATO Next-­‐Genera9on Autonomous Systems Joseph Rice, Naval Postgraduate School U.S. Seaweb is a through-­‐water communications network
• Telesonar digital acoustic modems from Teledyne Benthos, Inc.
• 9-­‐14 kHz acoustic signaling
• Data packets up to 4 kbytes at 800 bit/s • Sensor nodes and repeater nodes with wide-­‐area network routing
• Racom (radio/acoustic communications) gateway node at the sea surface
• Iridium SATCOM from Racom to Seaweb server at ashore command center

Payoff to the Navy • Advancing distributed architectures and technologies for underwater networked sensors. • Inspiring ASW system concepts and enabling interoperability across missions & na@ons. Objec9ve • Develop through-­‐water networked communica@ons for distributed ASW systems. Deliverable • Seaweb capability suppor@ng NGAS Joint Research Project. Milestones • NGAS09 sea trial networked 7 NOR and USA sensors against a coopera@ve ITA Sauro-­‐class SSK. • NGAS10 advanced Seaweb func@onality and networked 20 nodes from CAN, NOR & USA. • NGAS11 asynchronously networked coali@on sensors with cueing to downrange ASW assets. • NGAS12 networked 20 nodes from CAN, DEU, NOR, and USA. Accomplishments to Date • Opera@onal Seaweb WAN. • Experimental Seastar LAN. • Deep Seaweb concept. • 20 relevant NPS theses. NATO NGAS/GLINT 2011 joint sea trial Seaweb
