NMEA Router is a freeware computer software (developed by Neal Arundale) which can be used as an AIS-data forwarding utility. Thus, if you own an AIS receiver with a serial output and you wish to share your AIS-data with MarineTraffic, you may use this utility. The program has been developed with AIS data in mind which is encapsulated within a certain type of an NMEA sentence.
NMEA Router routes NMEA sentences from a Source (for example, an AIS Receiver's Serial Port) to a Destination (for example, the MarineTraffic database).
A Source or a Destination is called a Connection. A Source is linked to a Destination by a Route (for example the data from your AIS Receiver being routed to MarineTraffic).
