AIS

The Automatic Identification System (AIS) is an automatic tracking system that uses transponders on ships and is used by Vessel Traffic Services (VTS) to determine ship position. AIS information supplements marine radar, which continues to be the primary method of collision avoidance for water transport.

CLASS B AIS

V3100 Class B AIS

SKU: 000-14380-001

Increased Transmission Frequency and Reliability
The V3100 Class B AIS incorporates the same SOTDMA technology found in Class A solutions. This self-organising transmission technology allows the system to negotiate a regular transmission timeslot with other AIS units in range, facilitating more frequent and reliable position updates in high-traffic areas. The V3100 transmits updates, based on vessel speed, up to once every five seconds; this provides up to six times the reporting frequency of standard Class B AIS.

Increased Transmission Range
The V3100 features a maximum transmission power of 5 Watts, 2.5 times the transmission power of standard Class B AIS solutions. This allows vessels equipped with the V3100 to be detected over AIS at a greater range, and provides more reliable transmission to satellite-based AIS receivers.

Integrated ‘Black-Box’ Solution
This ‘black box’ AIS solution is designed to work with Simrad multifunction displays, and other NMEA 2000® or NMEA 0183® connected marine electronics. Output to a standard PC is also supported via USB connectivity. The V3100 is contained in a compact IP67 water-resistant housing, and includes a built-in SD card slot for standalone AIS data logging.

  • Greater transmission reliability in high-traffic areas

  • Integrated “black-box” solution

  • NMEA2000, dual NMEA0183 and USB connectivity

  • IP67 water-resistant housing

  • Built-in SD card slot for AIS data logging

 

NAIS-500

SKU: 000-13611-001

Reduce your risk of collision with this fully integrated, Class-B AIS transponder - essential for navigating today’s busy shipping lanes and congested ports. Compact in size, lightweight only 250 grams, fully waterproof (IPX7), with low power draw and featuring multiple connections, the NAIS 500 is ideal for networking with any NSS, NSO, or GO series chartplotter / multifunction display and Simrad RS VHF system.


The NAIS 500 ensures that you are seen and can see on the water by sending a signal to other vessels with your navigational data, whilst you receive data from other vessels. This allows you to plan any necessary avoidance manoeuvres well in advance.

Compatible with NMEA 2000®, NMEA 0183®, NMEA 0183® multiplexing and USB. The NAIS 500 features a low average power consumption of 180 mA at 12 VDC.

CLASS A AIS

Class A is intended for vessels where the fit is mandatory. Class A transmits more information, more frequently and at higher power than Class B. AIS information from a class A transponder will always be prioritised and, thus, be shown to other ships in the area, whereas AIS information from a class B transponder will not be shown until or if there is room on the AIS channel.
