The ATA100 AIS Transponder is a fully compliant Class A transceiver designed to complement the existing range of maritime safety equipment from Ocean Signal. Used as an aid to collision-avoidance, the ATA100 combines the trusted technology and fluid product design that have become synonymous with Ocean Signal products.


This compact, single unit solution is capable of exchanging dynamic and static ship data with other AIS systems. Real time marine traffic information is continuously interpreted using a powerful internal processing engine and displayed on a 7” full-colour, rapid-response LCD. The coastline map view and radar view have various orientation display options allowing for user preference whilst a standard target list display gives immediate detailed listings of nearby vessels which can be sorted to the owner’s desire.

The AIS message-sending functionality is simple to use, ensuring safety related messages can be quickly delivered or received by the user with very little effort. An instant message and alarm function provides immediate notification of any potential problems or hazards including the deployment of Ocean Signal’s MOB1, the world’s smallest Man Overboard AIS/DSC device. It is also compatible with all other AIS Man Overboard devices including ACR’s AISLink MOB.’


Dynamic data such as location, speed over ground and course over ground is calculated automatically using the integrated 99-channel GPS receiver, while the static and voyage related data such as MMSI, call sign and name, type of ship, destination, ETA etc. is easily programmed into the AIS transponder via a user-friendly menu interface.


This single unit solution to meet AIS requirements ensures a minimal use of bridge space and its surface or free standing mounting options allow for easy installation into almost any position or location. It also includes multiple connectivity options including WiFi, USB port, serial and Pilot plug.


The ATA100 AIS Transponder Class A unit from Ocean Signal meets the requirements of the EU MED (Wheelmark) Directive and USCG/FCC regulations. It also complies with the EU Inland Waterways standard, administered by the CCNR.
