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.

The A052T Class B+ Transponder can be powered by a power supply ranging from 12v to 24v.
Step 3 – What do you want to see?
The Class B+ Transponder will broadcast your location and receive AIS signals.
- A VHF antenna – to collect and transmit the AIS data
- If you want to use the same VHF aerial as your radio communication, use a splitter.
- A GPS antenna – to pinpoint location.
Step 4 – Transmitting your location (ON/OFF)
You can decide when to transmit your location using STANDBY mode in configuration software.
Step 5 – Choosing your Transmitting power
The default is 5 Watts, changeable to 1 or 2 Watts.
Step 6 – Which screen/s will you connect your A052T transponder to:
- NMEA 0183 Chart plotter
- Windows or Linux laptop
- Up to 4 wireless devices
- Wireless devices through router in Station mode WiFi
- NMEA 2000 chart plotter
Who will be able to see my transmitted AIS signal?
Nearby ships, even in poor visibility, plus online AIS services.
