AISmon can be used to convert NMEA data from an audio source. You can utilize either a radio receiver (VHF receiver or transceiver) or an SDR receiver for this purpose. This method offers a cost-effective alternative to specialized AIS receivers, as it allows you to use a budget-friendly or readily available VHF device along with a PC equipped with a simple sound card (with Line-In) to decode AIS messages. However, note that you may need to tap into the discriminator output of the radio.

The setup process can be relatively complex, depending on the device, and might require additional software to provide AISmon with the necessary audio source. Once the audio source is set up, AISmon will handle the decoding of incoming AIS data and forward it to our database. This guide covers only the setup of AISmon and does not address the prerequisites, which can become quite extensive depending on the receiving device or the Windows operating system used.

AIS Decoder and Forwarder

Pro

  • Decodes AIS data from audio

Contra

  • only available for Windows

  • Outdated

  • Can only monitor one AIS channel

Requirements

  • You have configured an audio source that needs to be decoded

  • You have requested to share AIS data and have received the IP and port information

  • Your operating system is supported by this software

Configuration

  • Select the audio source to be used under Audio Device

  • Ensure that the Sampling Rate is set to 48,000 Hz

  • Activate "Monitor audio input and minimize..."

  • Enable UDP Output and enter the IP address and port number you received

    • Use a colon (:) to separate the IP address and port (5.9.207.224:12345)

  • klick Start Monitoring to decode the Audio and forward the data

Next, access your station on MarineTraffic to verify if the data is being received. Please allow a few minutes for the statistics to reflect a successful reception.
