• Answers
• Where am I
• Where are they
• Also Answers
• Who are they
• Which way are they headed
• How fast are they going
• and much more

A View From the Bridge

• Mariner can choose to integrate AIS information
  into the bridge management system in a number of
  ways
• ECDIS Overlay
• ECS Input
• ARPA
• PC
• One data string - many ways to display

Ship To Ship AIS

• Raises safety across the board
• Most desired feature
• Provides situational presentation
• on bridge
• Technology exists
• Product evolving

Enhanced AIS
NON - CG Sources Weather Currents Depth PORTS Etc.
CG C2 Node
Alerts / Alarms
Waterway Info
Watchstander
Smart Tree

• Low solution to many traffic management issues
• Maintain coverage in electronically blind areas
• Insert emergency information from a C2 Center
• May be integrated as part of NDS
• Single Infrastructure /Multi-Mission capability
• NOT a VTS but could transition to an emergency
  VTS
• can remotely manage TSS, Maritime sanctuaries

Vessel Provides ID, position, course, heading,
speed Vessel Receives Information on vessels,
port data, and hazards in area
