Secure AIS

26 September 2009

Secure AIS The AIS broadcasting standard is excellent for information sharing between commercial ships at sea and between ships and shore stations. This open information sharing is however not suitable for users like Navy, Coast Guard, Police, etc., who have a need to exchange secure information between their own assets and still be able to receive the open AIS information.

Saab TransponderTech has developed the Secure AIS solution, which satisfies these requirements. The Secure AIS functionality has been developed concurrently for the R4S Secure Shipborne AIS transponder, the R4AS Secure Airborne AIS transponder, the Saab R40S Secure Base Station, the Saab AIS network infrastructure and presentation systems, in order to create a complete solution. Upgrade options are available for existing, qualified users of Saab TransponderTech AIS products and systems.

We offers real-time Met/Hydro systems for docks, ports, harbour and fairway, marine terminals and offshore, as part of our standard system deliveries. We are the system integrator of the systems and components used to measure wind, pressure, visibility, sea and air temperature, sea currents, waves and tides. Data from systems can be collected and distributed at customer’s own preference.

Knowledge of current speed and direction in real-time at multiple depths will increase navigation safety and guide vessels to the correct entrance based on size, cargo and displacement. This is especially valuable when performing difficult maneuvering and in narrow areas.

Our AIS MetHydro solution has been designed around a standard AtoN device developed for the marine industry by Automatic Power Inc. This Transponder unit is a fully automated system, once it has been installed and turned on, no maintenance is required to keep it operational. The AIS AtoN unit is fully compliant with the IMO specifications.

The purpose of integrating AIS and MetHydro data :

Provide real time MetHydro information on existing AIS system for ships sailing along the coast on IALA, IMO and IEC standards.
Ships have to have up to date AIS display system on board in order to see data
A safe and operational system for Governments and Maritime authorities.

Remote Monitoring System for Aids to Navigation

01 July 2009

AIS AtoN is a special type of AIS transceiver fixed to any navigational aid (e.g. buoy or lighthouse). An AIS AtoN provides real-time status and positive identification of the AtoN to surrounding vessels and shore stations.

Our solution can automatically acquires battery voltage, lantern current, and lantern on/off data, and sends it as an addressed binary Message 6 to the AIS management centre. It has been developed to provide reliable information feeds into AIS systems and networks, this technology is designed to operate in remote fixed locations such as buoys and shipping hazards.

Automatic Identification System (AIS)

01 July 2009

AIS Positional information of vessels is particularly crucial for collision avoidance. Conventionally, such task was implemented using radar system. Advancement of technologies particularly GPS and wireless and increase in waterway safety requirements respectively have made possible and demanded a more effective and efficient solutions. AIS leverages on these new technologies to serve the purpose

The core function of the system is to identify, obtain positional and navigational related information of all the surrounding vessels.

Conventional radar is only capable to detect nearby vessels but is not able to identify them in order to communicate with them thru other means such as radio. Radar system is also less reliable during extreme weather and interferences.
