How to contribute AIS data?

Using ShipPlotter

If you would like to contribute AIS data from ShipPlotter, click on Options->Sharing->Server and set:

  • Server:
  • Port: 80
  • Script: shipinfo.php

The 'forward data from server 1 to server 2' box should not be ticked if you are sharing with the COAA server. Please only upload your own AIS data to AISLiverpool.

AISLiverpool is an "upload only" server so the "upload only" and "Trust static info" options have no effect.

ShipPlotter sharing option

Alternatively, you can directly upload to

  • Server:
  • Port: 80
  • Script: shipinfo.php
Uploading to either AISLiverpool or ShipAIS should be equivalent. ShipAIS tends to have a quicker response, but I have better loging facilities at AISLiverpool in case there is a problem.

Raw AIS NMEA or AIVDM data

If you are not using ShipPlotter, you can also upload unprocessed AIS data to

  • (
  • Port: 4000
  • UDP data
