AIS - Frequently Asked Questions

What is AIS?
AIS (Automatic Identification System) AIS, which stands for Automatic Identification System, is at its most basic level an electronic transponder installed on a boat or vessel that continuously transmits a VHF signal containing information including its name, call sign, type and position.
You can read more at Wikipedia AIS page.
What is AIS Network? AIS network is a database containing real-time information on over 100 thousand ships worldwide and constantly growing.
Data come from hundreds of AIS receivers all over the world.
The network is maintained by AirNav Systems which develops AirNav ShipTrax, one of the world's biggest professional AIS networks.
What do I need to see ships in my area?
To track ships on your location you will need:
- AIS Receiver;
- AIS Antenna;
- AIS Software.
The AIS receiver gets AIS data from ships and sends it to a computer using an USB connection.
A software running on your computer decodes this data so you can track the ships on a map.
How can I share my data so it seen on AIS network?
To share your data you will need a special software that sends data to servers.
If you already have this software contact the team so we can send you detailed software communication instructions (TCP-IP address and port to share data to).
This usually happens with users that already share data to other AIS networks.

If you don't have an AIS system please read below.
