View up to 300nm range AIS on your chartplotter.
The DataHub® now delivers global AIS data to your chartplotter and nav apps, with Over the Horizon AIS (OHA)
Stay safer with 300nm AIS visibility.
Over the Horizon AIS (OHA) increases your AIS range from as low as 5nm to 300nm! If you are sailing at 10 kt using regular AIS and a container ship is sailing directly towards you at 25 kt, you only have 8.5 minutes to react and alter course. On the other hand, OHA would provide you with 8.5 hours warning time.
Some chart plotters cannot display the full 300nm AIS range. For example, Garmin cuts off at 75nm.
Powered by the DataHub®
The DataHub has access to the entire global AIS network via your existing internet connection and knows your exact gps location. It then downloads all OHA vessel positions within 300 nm of your current location.

“We’re delighted to have added the DataHub to our navigational bag of tricks. It enables me to download the AIS position of vessels up to 300 NM away from us.”

“The PredictWind DataHub that supports “Over The Horizon AIS” provides a layer of safety for Sea Dweller and her crew that is unprecedented.”

A world-first for AIS.
The DataHub downloads the OHA data approximately once every minute. It is then converted into NMEA and shared to your vessel's instrumentation over WiFi.
OHA targets are displayed on your nav display in the same way as regular AIS targets. When a vessel is located via VHF and OHA, only the VHF data will be displayed.
OHA data can be downloaded via your existing Starlink, Iridium GO! exec or cellular internet connection.
Never be without AIS.
OHA also works as a backup should your standard AIS receiver fail. Ensure you are never without AIS data, which is critical for collision avoidance, security, navigational safety and search and rescue.
