The ideal transponder to fulfil your local Class B legal requirements, as well as for peace of mind and project tracking,

This is the ideal, compact AIS transponder.

 

In addition to transmitting your AIS information to local boats and receiving stations, the A051T will also decode incoming AIS messages.

The A051T will receive and decode your GPS location as well as the AIS messages from local ships. Combining the AIS and GPS data, you will be able to view which  other boats and ships are around and your position compared to them and the coastline.

You can view your AIS and GPS data on

  • up to two chart plotters
  • your laptop, computer or tablet through USB OTG(Android or Linux compatible)
  • up to 4 WiFi enabled devices

Straight forward setup.

Find out whether you need a Class A or Class B transponder 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 A051T, compared to most other transponders.

.

Step 2 – Choose your power source

The A051T 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 A051T 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 –Which screen/s will you connect your A051T transponder to:

  • Chart plotter NMEA 0183 RS422
  • Chart plotter NMEA 0183 RS232
  • 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

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.

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 QK-A051T Transponder 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.

Pre-configuration service

Pre-configuration service

If you order the Pre-configuration service we will pre-configure your transponder with your MMSI number, ship type and any other required information (Particularly useful for customers who do not have access to a Windows system).

NOTE: Some of this information is required by law for CLASS B transponders. The customer is responsible to check what other fields are required in their location.

The minimum information we require is the MMSI number and ship type (Any un-required fields can be left blank).

.

The following data can be pre-configured, if specified.

MMSI – The Maritime Mobile Service Identity number is your unique 9 digit number that is assigned to a DSC (Digital Selective Calling) radio or a transponder unit. See chapter in manual on Mobile Maritime Service Identity.

Ship type – This field should contain a number referring to the type of vessel you are using this transponder on. For example ‘36’ for vessels using sail propulsion. And ‘37’ for pleasure craft (Yacht powered by engine).


GPS (A, B, C, D)

A: Distance from bow to GPS antenna in metres
B: Distance from stern to GPS antenna in metres
C: Distance from port to GPS antenna in metres
D: Distance from Starboard to GPS antenna in metres

(The transponder must know where your GPS antenna is located to make accurate readings.

Be as accurate as possible when writing this information as it will impact on the accuracy of your GPS data.)

IMO – International Maritime Organization number should be entered into this section, if relevant. This can be found on the hull and certificates for the ship.

CALL SIGN – Your vessel’s call sign if relevant.

Draught – The vertical distance between the waterline and the bottom of the hull (keel), with the thickness of the hull included. Draft determines the minimum depth of water a ship or boat can safely navigate.

Name – Name of your vessel.

Destination – This is the destination your vessel is heading to. This should be entered before every journey.

ETA – Estimated time of arrival to destination entered above.

[1] Manually adjustable hopping interval rates (0.25 seconds, 1 second, 30 seconds and auto-hopping) Channel hopping will increase the number of messages received, in comparison with single channel receivers. However, part of some multi-AIS messages may be lost, due to the hopping nature of the product. If both the quantity and the completeness of AIS messages is important to you, we recommend the dual channel receivers.
