ENOS Rescue-System

ENOS is the abbreviation for electronic alarm and tracking system. The ENOS system is a rescue system that has been developed specifically for water sports, mostly for diving, but also for windsurfing, sailing, motor boats. With the help of ENOS system, people who float on the water surface and are in need, be quickly located and rescued.

The ENOS system is a development of the company Seareq Safety and Rescue Equipment, based in Rösrath. The launch was in 2004 and since then it is in use in the following countries: Egypt, Ecuador / Galapagos, EU, Maldives, Seychelles and since the autumn of 2008 in Australia and the United States. Due to its life-saving character, it is considered by many international diving associations officially recommended.

Design and functional principle

The ENOS system consists of two units: the ENOS receiver on board the dive boat and enjoy an ENOS transmitter, which leads the diver during the dive with them.

Both units are supported by GPS. That is, the receiver and transmitter to determine with the help of the GPS satellites, the GPS coordinates of their respective position. For emergency transfer, the ENOS system is equipped with an unlicensed radio frequency.

From the positions ( A) and ( B) the receiver calculates the distance and direction to the distressed divers and shows this in an easy to understand graphic on his screen.

Technology and range

The ENOS system is a rescue system that works in the local area. The scope of the emergency call is dependent on the height of the receiving antenna of the ENOS receiver on board the ship and on the environmental conditions. The higher the antenna is installed, the greater the range. Under optimal conditions, the emergency of ENOS system reaches up to ten kilometers. Transmission ranges up to five kilometers are standard.

The radio frequency of ENOS system is license - free and approved. It depends on the national radio laws in the countries in which it is inserted. This provides operators arise by an application ( bailout ) no cost. As the rescue system ENOS system is structured so that each ENOS receiver can receive all emergency calls from all ENOS stations broadcasting on the same frequency and are in the reception area.

The ENOS system is the only salvation for the water system, which transmits the GPS location of the emergency call ends right around the world.

Other rescue systems

Unlike other rescue systems and man overboard systems, the ENOS system is not equipped with the international emergency frequency. The emergency call is sent directly to the ENOS receiver and not to coastguards and other rescue authorities (eg MRCC ). This has the advantage that the submersible ship that the person driving is closest, just can not initiate the rescue operation.

Rescue systems that transmit the distress call on the international distress frequency, working nationwide. You have the purpose to transmit the position of ships or persons in distress on the high seas come alone to international emergency rooms. This has the advantage that the emergency call is received even at great distances and still help can be initiated.
