Alion Science and Technology
eMSI Demonstration What Distribute electronic Maritime Safety Information (e-MSI) information using the Automatic Identification System (AIS) When Project started early 2016 Where Along a reach of the Lower Ohio River and adjacent reaches of the Mississippi River upstream and downstream from Cairo Why Enhance the safety and efficiency of navigation along inland rivers Alion Science and Technology 9/19/17

Alion Science and Technology
Message Creation Automatic From database such as USACE LPMS, NOAA, NGS, etc. Fetcher/Formatter to get data, assemble message in proper format, send to transmit chain Manual User-created, such as a Geographic Notice Standard must be defined ASMs Embedded in NMEA BBM (or VDM) sentences Alion Science and Technology 9/19/17
7
Automatic Message Creation
If the information already exists and can be accessed, it can be collected, organized, prioritized and transmitted as an AIS message Alion has already developed software that can be configured to meet commercial, USACE and USCG end-user needs. Alion Science and Technology 9/19/17
8
Manual Message Creation
Some message types (GN for example) require information from a person Alion Science and Technology 9/19/17
9
Environmental Message
Used to report met/hydro information Water levels (pool gauges) Water current Wind speed/direction Temperature Weather Air gap Alion Science and Technology 9/19/17
10
Waterways Management Message
Used to facilitate vessel traffic movement in confined waters List of vessels through a point Vessels awaiting lockage Procession Order Enter/exit port Bridge Narrows Gate Alion Science and Technology 9/19/17

Alion Science and Technology
Message Routing Getting the message from the source to the desired transmitter or transmitters According to the area the content of the message applies to (i.e., “broadcast”) To reach a specific addressee (auto or user-specified; i.e., “addressed”) Implemented by “AIS Router” CNS DataSwitch for example To route messages needs TAG destination parameter Ideally would like to shield the user from the TAGs and let user select based upon geography… Alion Science and Technology 9/19/17
13
Alion Science and Technology
Message Queuing Functionality missing from other components is added by ASM Manager software Ensures messages are valid before transmission Buffers the incoming messages Allows for message prioritization Allows for geographic restriction [Message Routing] Manages the queue of messages Ensures all messages are transmitted [VDL Monitoring] Guarantees transmission [Message Transmission] Sender acknowledgments [VDL Monitoring] Message repetition Alion Science and Technology 9/19/17
