AIS Decoder is an AIS-data forwarding utility (developed by Neal Arundale) which can be used if you own an AIS receiver with a serial.

Lower Manhattan Immingham UK Docks Introduction Ais Decoder accepts AIS data from an AIS Receiver, the Internet or a Local Network connection, decodes the data and presents the decoded data in a form suitable for display and analysis by mapping program (eg Google Earth or Google Maps), or for analysis using Excel, or by a database (eg MySql). Main Features Input: Serial or USB from AIS receiver, UDP or TCP from network, Log File Input Filter: AIS Message type, DAC, FI, ID, MMSI Output: Display, File, FTP, UDP Output Frequency As received or at Scheduled intervals Output Filter: Lat/Lon or any other decoded field Output Formats: Text, CSV, HTML, XML, KML, KMZ, NMEA Self-extracting installation file, including help PDF Help Manual AIS AIS is primarily transmitted by ships for collision avoidance.

Ships over 200 tons must carry an AIS transponder which both transmits and receives AIS data, enabling vessels to see the speed and course (and other information) of vessels within around 20 miles of one another. It is also used by the Coast Guard and port authorities to monitor vessel movements. Other uses are becoming more common, such as Virtual Navigation Aids, weather and sea state reporting, control of inland waterways such as canals and locks. Anyone with a suitable receiver can receive this data.
