A052T 5W SOTDMA Class B+ WiFi & NMEA 0183/2000 AIS Transponder

Description

Looking for an essential piece of marine equipment? Look no further.

The A052T Class B+ AIS Transponder is the perfect solution for broadcasting your vessel’s details — including location, name, dimensions, speed, and more.

Compact and reliable, the A052T not only meets your local Class B+ AIS compliance requirements, but also offers enhanced safety and project tracking capabilities.

In addition to transmitting your AIS data to nearby vessels and shore stations, the A052T also receives and decodes incoming AIS messages — just like our dedicated AIS receivers. It integrates GPS data with AIS signals, allowing you to accurately track your own position and see other vessels in your vicinity in real-time.

Display your AIS and GPS data on:

• Chart plotters via NMEA 0183 or NMEA 2000 connections

• Laptops, computers, or tablets via USB OTG (compatible with Android and Linux)

• Up to four WiFi-enabled devices simultaneously

Whether for safety, compliance, or enhanced situational awareness, the A052T is the all-in-one AIS transponder you can rely on.

Features:

• Transmits your vessel’s position, speed, heading, and other key data to nearby vessels and AIS receiving stations within VHF range.
• Receives and processes all AIS message types, as well as GPS data.
• Monitors the position, speed, and heading of other AIS-equipped vessels within VHF range.
• Tracks movement of nearby AIS vessels in real time, displaying their course, speed, and heading changes on a PC, chart plotter, or wireless device.
• A cost-effective solution for collision avoidance and maritime monitoring.
• Fully compliant with all required standards under the European RF & TTE directive.
• Real-time LED indicators confirm successful transmission and reception of AIS messages, giving you confidence the A052T is working correctly.
• Supports web-based configuration via WiFi.

Technical Summary:

• AIS transmission rate: 5 Watts, SOTDMA protocol. Programmable between 1, 2 and 5 (by default) Watts.
• AIS receiving range: Up to 40nm.
• VHF connector port: Standard SO239/UHF Female connector. Connects to an external VHF/AIS antenna (requires standard PL-259/UHF Male Plug)
• GPS connector: TNC female bulkhead connector for connection to an external GPS antenna. The A052T includes a built in GPS module and only requires a GPS antenna to be connected
• POWER connector: 12 pin POWER/NMEA connector
• POWER supply range: 12V – 35V
• NMEA 0183 output ports: For connection to chart plotters and other NMEA0183 compatible equipment as desired.
• USB: Type C USB for easy connecting to your laptop or PC for configuration and data viewing. (Please note, full configuration is only possible via a Windows PC where as the Vessel information can be configured via WiFi.)
• WiFi Output: The NMEA 0183 sentences are also transmitted through WiFi. It support Ad-hoc and Station mode WiFi (with and without a router). No configuration required for Ad-hoc WiFi.
• NMEA 2000 Output: Connects to NMEA 2000 networks for AIS and position data sharing.
• LED lights confirm incoming and outgoing AIS messages, GPS, WiFi and Power.

Find out whether you need a Class A or Class B+ transceiver here.

Perfect for use in all Class B+ boats (under 300 tonnes etc.): sailing boats or yachts, small fishing boats, etc..

Easy to install and use…

Step 1 – Decide where to put your transponder on your boat

A key advantage of this Class B+ Transceiver is that we’ve encased it in aluminum – to minimize interference from other equipment. This opens up many more places you can install the A052T, compared to most other transponders.

Step 2 – Choose your power source

The A052T Class B+ Transponder can be powered by a power supply ranging from 12v to 24v. This covers most power sources used on boats, and is a distinct advantage over transponders that are powered only by a 12v power supply.

Step 3 – What do you want to see?

The Class B+ Transponder will of course broadcast your location – but in addition it also receives AIS signals from other ships in your area and receives your GPS location.

Your A052T transponder has input ports where you simply connect your aerials.

You will need to install two aerials:

• A VHF antenna – to collect and transmit the AIS data
• (If you want to use the same VHF aerial as your radio communication, simply use a splitter before connection.)
• A GPS antenna – used to pinpoint your accuate location

Step 4 – Transmitting your location (ON/OFF)

As this is a Class B+ transponder, you can decide when (or if) you want to transmit your location, using STANDBY mode in the Configuration software.

Step 5 – Choosing your Transmitting power

By default, the A052T is set to 5 Watts for the AIS Transmission power, however this can be changed down to either 1 or 2 Watts. This can help improve safety at sea. The higher the Watts, the further the signals transmit.

Step 6 –Which screen/s will you connect your A052T transponder to:

• NMEA 0183 Chart plotter via NMEA 0183 output
• Windows or Linux laptop (using the USB input or WiFi)
• Up to 4 wireless devices (phones, tablets or laptops) in Ad-hoc mode WiFi
  
• Wireless devices through your Access point/router in Station mode WiFi
• NMEA 2000 chart plotter through NMEA 2000 backbone

This Transponder works in both WiFi modes, Ad-hoc and Station modes:

Who will be able to see my transmitted AIS signal?

Nearby ships will be able to view your details using their AIS receiver, even in bad weather and poor visibility.

Around the world, AIS data from most ports, coastlines and internal waterways is uploaded to the internet by the local community. This means that, if you are in one of these areas; your teammates, partners and loved ones will be able to view your location, using one of the free online AIS websites, from anywhere in the world.

Whether for peace of mind or project tracking, this can be very useful. Find out more here.

What’s included?

• 1 x A052T AIS Transponder (class B+)
• 1 x 12 pin POWER/NMEA cable
• 1 x USB Type C cable

Available to add to your order:

• AS12 AIS/VHF Fiberglass Antenna
• AS14 Waterproof GPS Antenna

IMPORTANT: Class B+ Transponder

AIS transponders themselves don’t need to be registered, however, each requires a unique and official 9-digit Maritime Mobile Service Identity (MMSI) number assigned to the vessel and its owner.

To obtain an MMSI number, you should contact the relevant authority in your country. Different countries have different authorities responsible for this service. If you are not sure, search ‘how to apply for an MMSI in (country name)’

Please Note: The A052T Transceiver will allow you input an MMSI number only once.

Please make sure you input the correct MMSI number before clicking ‘config’, as changes are not permitted after confirming.
