NASA AIS Engine 3
NASA AIS Engine - latest Version 3 model

Commercial vessels over 300 tons and all passenger vessels are required to have installed an AIS (automatic identification system). This equipment transmits ship name, MMSI number, position, speed, course and heading every few seconds. It enables other vessels and port authorities to get a better picture of what's happening around them - a bit like air traffic control. The AIS engine receives AIS data and converts it to NMEA format and then sends it to any display equipped to receive it. The engine can also receive NMEA information from a GPS receiver (at 4800 baud) which it cobmine with the AIS data (at 38,400 baud). Please check compatibility of AIS input within your chartplotter or software before buying.
