Simrad Automatic Identification Systems
Smaller boats can easily go undetected by radar systems on larger commercial vessels, because the radar’s line-of-sight can be
blocked by the superstructure of the ship or can also miss the boat due to the high placement of the radar antenna. This can easily
exceed 30 meters over the sea level. The AIS is not line-of-sight and the range is typically about 20 nautical miles. This is one major
reason why large commercial vessels are required to carry an AIS-transponder.
AIS focuses your awareness on all vessels in your vicinity and helps reduce the risk of collision by exchanging safety data between
them, such as: Vessel Name, Size & Call sign - Maritime Mobile Service Identity number (MMSI), Vessel Type, Time to closest point
of approach, Course, Speed and Heading.
Simrad is currently the only major brand that offers NMEA2000/SimNet compatible Class-B Transmit and Receive AIS transponder
systems, both as an integrated standalone product with colour display (AI50) and as a black box solution (NAIS-300) designed for
use with any AIS-compatible multi-function display product.
