Automatic Radar Plotting Aid

Automatic radar plotting aids are required for ships of 10,000 gross tons or more, constructed on or after September 1984, and tankers constructed before September 1st, 1984. It is designed to be operated as a separate or integral part of marine radar equipment. It will give precise target information to avoid collision in vector and numeric form. There are various models world-wide. Please ask a representative about detailed specifications. Listed below are some specifications for your reference.

Azimuth Mirror

A measuring instrument used with the magnetic compass. For obtaining the azimuth of observed objects by observing an object’s reflection in a mirror or prism, pivoted in the centre of glass over a compass card.

Direction Finding Apparatus

Ships constructed on or after May 25, 1980 exceeding 1,600 gross tons or more shall be fitted with direction finding apparatus. Automatically indicates ships true bearing by reading frequencies from two or more radio beacon broadcast stations or transmissions from other vessels.

Echo Sounding Device

For ships constructed before May 25, 1980, weighing greater than 1,600 gross tons and for ships constructed after May 25, 1980, weighing greater than 500 gross tons. All vessels falling under this classification which sail international routes must be fitted with an echo sounding device. Electrically operated instrument that emits a sound from vessel’s submerged surface and then measures and records the time interval which passes before the echo returns. The most popular model is shown here. Please ask for further information and brochures of various models available from local manufacturers when required.

Gyro Compass

Ships of 500 gross tons or more constructed on or after September 1st, 1984 and ships of 1,600 gross tons or more constructed before September 1st, 1984 shall be fitted with a gyro compass. The gyroscope is mounted, ballasted and fitted so that it’s north south line always remains within the meridian through the influence of the earth’s diurnal revolution. Can be used as a sensor for the following types of navigation devices : Autopilots, Radar, Collision avoidance systems, Satellite navigation systems, Direction finders, etc. Here are some specifications as a reference when ordering.

Magnetic Compass

A compass which measures direction by a needle which continuously seeks the magnetic meridian. SOLAS Regulation requires ships of 150 gross tons or more to be fitted with a magnetic compass. Here are some types of magnetic compasses for your reference. There are several sizes of compass card diameter, according to the type of magnetic compass and the manufacturers.

Radar

Electronic system by which the bearing and distance of an object are found by the emission of a radio pulse. An object’s bearing and distance can be measured by observing the direction from which the pulse returns and the time elapsed from when it was sent. Ships of 500 gross tons or more constructed on or after September 1st, 1984 and ships of 1,600 gross tons or more constructed before September 1st, 1984 shall be fitted with a radar installation. From February 1st, 1995, the radar installation will be capable of operating on the 9 GHz frequency band. In addition, cargo ships of 300 gross tons or more, when engaged on international voyages, shall be fitted with a radar installation capable of operating on 9 GHz frequency band.

Weather Facsimile Receiver

Weather facsimile service is provided world-wide, and designed to meet the WMO (World Meteorological Organization) standards. The most popular model is shown here. Please ask for further information and brochures of various models available from local manufacturers when required.
