Every ship the network hears, on one chart.
Open AIS feeds and volunteer receivers, gathered on our own server. Free to look at, no account. Each light below is where ships are heard right now.
Where every ship comes from
The chart keeps the name of the feed with each ship. The bar shows how many ships each feed heard in the last 24 hours; "only here" counts ships no other feed heard.
Receivers run by people who share what they hear
Each volunteer station has its own page. It is private until its owner makes it public. Tap a station to see the ships it hears right now.
Dark coasts are not empty. They are unheard.
A receiver near the water lights up its stretch of coast. How far it hears is set by height, as at sea: VHF reaches about to the radio horizon of both antennas.
How far would yours hear?
What you need
- An AIS receiver: a USB radio stick made for AIS, or a dedicated AIS receiver.
- An antenna for 162 MHz, as high and as clear as you can put it.
- A small computer that stays on (a Raspberry Pi is enough) and an internet connection.
What you get
- A page for your station: the ships it heard, where, its best range, and the ships only it heard.
- You keep your rights to your data. No exclusivity: feed any other network at the same time, stop whenever you like. Sending data means accepting the station terms: Gangway may use it in its products, including paid ones.
- The ships off your coast appear for every seafarer and their families.
Ports we used to hear
Ports where the feeds heard many ships before and few or none in the last six hours: a receiver there went quiet. One receiver nearby would bring them back.
What you can do with it
Look at the live chart, search a ship or a port, follow one.
