True Heading AIS MOB

The new AIS-MOB unit from True Heading is a combined AIS MOB/DSC Maritime Survivor Locating Device (MSLD).

It is developed to increase the efficiency of Man over Board emergency alerting to the vicinity according to all existing standards by starting broadcasting within seconds after activation.
Base of this device is the world’s first AIS MOB unit with full automatic activation.
Goal of the AIS-MOB is to fasten-up the alerting of the “next to the MOB” vessels. The combination of these two most effective communication ways will be the result which probably can make the difference between saving or losing a life at sea.
Due to the palm size the AIS-MOB is ready for easy usage with every kind of automatic life jackets, no matter which manufacturer. With a bright red LED flare the AIS-MOB has got a high visibility for miles.

Function

Mounting into life jacket
The MSLD AIS-MOB just has to be placed between the folded blatter of the life jacket.
First open-up the zipper of the jacket a bit that the small rope of the AIS-MOB can be fixed by a knot on a given D-ring or something similar. After that the AIS-MOB has to be slided upside down in between the blatter. Finally the zipper has to be closed again.

In event of emergency

Automatic activation
In case of man over board scenario the life jacket inflates automatically when submerged. The inflating of the balloon will throw out the MSLD AIS-MOB which also will be submerged into the water. The unit is triggered and starts broadcasting immediately.

Broadcasting DSC distress call
With the MOB AIS-MOB it is possible to alert up to 8 different vessels within a closed loop call. MMSI of these vessels can be programmed into the AIS-MOB easily via Bluetooth© and the free of charge Weatherdock-App. Within seconds after the automatic activation the first DSC distress call will be send out to all pre-programmed MMSI numbers containing the unit-ID of the MOB. This first alert will sensitize all the “closed loop vessels” about the event of emergency. After there is a position-fix with the satellite a second DSC distress call is send out to all pre-programmed MMSI numbers containing the unit-ID of the AIS-MOB as well as current GPS position of the MOB.

Broadcasting AIS safety message
Parallel to the DSC distress call an AIS safety related message will be send out after the MOB has got the position fix from the satellite. In case that the fix is ready, an AIS emergency message is send out to all AIS systems in the vicinity up to 7 nautical miles and more. The message contains the unit-ID of the device as well as live GPS position and speed and curse over ground of the victim drifting in the current. The GPS position will be updated every minute and send out with the next transmission.
