The "Polaric Server" is mainly a web based service to present (APRS)tracking information on maps and where the information is updated in real-time. It is originally targeted for use by radio amateurs in voluntary searchand rescue service in Norway. It consists of a web application and a serverprogram (APRS daemon).

This is a plugin that can read AIS data from a TCP stream and and presentAIS vessels as moving points on the map. It is used on aprs.no with data fromthe Norwegian Maritime Authority.

More documentation on the project can be found here:http://aprs.no/polaricserver
