AIS targets over Internet come from the global AISHub network, to which NavimetriX is affiliated.

The use and handling of AIS targets over Internet is exactly the same as for AIS targets received on board using an AIS receiver that transmits NMEA data to the application. For more details, see:

How to display AIS targets? in this FAQ.

Open the Settings panel (gear button at the top right)

• Select the AIS option
• Enable AIS over Internet

Cautions:

AIS targets over Internet should be considered for informational purposes only. Time delays due to Internet transfer speeds make them unsuitable for navigational safety, whereas reception on board by a dedicated receiver is at VHF frequency in real time.

They are therefore represented by blue icons to differentiate them from green AIS targets icons received directly.
