Marine Traffic - AIS

What is AIS?

AIS is initially intended to help ships avoid collisions, as well as assisting port authorities to better control sea traffic. AIS transponders on board vessels include a GPS (Global Positioning System) receiver, which collects position and movement details. It includes also a VHF transmitter, which transmits periodically this information on two VHF channels (frequencies 161.975 MHz and 162.025 MHz old VHF channels 87 & 88) and make this data available to the public domain.

The Point Souttar/Yorketown Radio Base & Port Victoria HQ both have AIS monitors that contributes to and shows on the map below
