See without being seen
The role of AIS in law enforcement and defence applications is becoming more important. It helps to identify vessels that show abnormal behaviour or even could be a threat. However, there are many situations in which a full view around a vessel is needed without announcing to the world that you are present. At the same time, it is necessary to stay in touch with the vessels in your team through AIS.
This is where the R5 Supreme W-AIS transponder proves its value. It features a secure mode in which all AIS traffic is received, but own messages are sent out through an encrypted radio channel that only authorized vessels can decode. It is the ultimate combination of stealth and situational awareness in AIS.
Public AIS operates on two global VHF channels, AIS1 and AIS2. The Saab Secure AIS link uses a third channel, selected by the user, ensuring minimum interference with public AIS communication. The Saab Secure W-AIS data link can be used in parallel with AIS1 and AIS2, giving the Saab Secure AIS users the complete AIS picture at all times.
