The main difference between MAIANA™ and all commercial AIS devices is that it is a self-contained unit, all AIS and GNSS circuits are located in the antenna housing

MAIANA™ receives GNSS and AIS data on both channels and can be enabled as a class B transponder. You are legally responsible for enabling the transmission, for more details read the full description.

The base kit connects via a Cat5 ethernet cable (not included) to a breakout board (included) to integrate it into your projects. Optionally, you can buy one of the 3 available adapters (USB + UART, USB + RS422 or USB + CAN) to facilitate connection with any on-board computer or any NMEA 0183/2000 network.

MAIANA™ is open-source, low consumption and is fully integrated into OpenPlotter.


The transponder outputs just over 2 Watts (+33dBm). It has a verified range of over 20 nautical miles on a masthead and 10+ miles on a pushpit.


MAIANA™ devices are not finished products, they need to be assembled by end users to function. MAIANA™ devices are distributed for research and development purposes. MAIANA™ devices are delivered with the ability to transmit disabled by default and have not been tested for compliance with regulations governing transmission of radio signals. End users are legally responsible for using the MAIANA™ device for transmission. We do not recommend to rely solely on MAIANA™ devices for navigation and collision avoidance.


Easy assembly. To complete the installation you will need:

  • A pair of strong scissors for cutting (thick) heat shrink tubing.
  • A heat gun for the heat shrink tubing. You will need this both on your workbench for the initial assembly, as well as on your boat for the final installation. Alternatives: How to Use Heat Shrink Tubing Without a Hot Air Gun.
  • 1” OD steel railing or a similar diameter fiberglass mast on your boat. This is the preferred way to mount the unit. You may, of course, use your own mechanism, but then you are responsible for sealing the (bottom) cable end from moisture.
  • A Cat5 cable for connecting the main unit to the breakout board in the cabin. Pick one with appropriate length and flexibility to suit your installation. The exact configuration of the cable (568A or 568B) is not important.
  • Some kind of instant glue to secure the end cap of the antenna tube.
  • If you are using the included breakout board you will need a soldering iron for the RJ45 connector and “breakaway” pin headers. All other optional adapters are mounted and soldered.
