The JLN-550 Doppler Sonar is designed to provide ship speed information with higher stability in the dual frequency modes; one using a lower ultrasonic frequency that is adequate to measure the ship’s speed against the ground up to larger depths and the other using a higher ultrasonic frequency that allows the ship’s speed against the water to be measured even in water with tiny bubbles. The transducer is designed for dual-frequency transmission, but its size is smaller than the conventional models.
Ship speed measurement is insensible to bubbles generated in high-speed navigation, ensuring stable speed display. The transducer is substantially downsized, allowing it to be installed on the bow side that is little affected by bubbles. An underwater-mateable connector is adopted for the transducer, so that a transducer can be replaced at a quay even in case of its failure. The equipment is provided with an additional function of indicating the ship’s fore and aft speeds and port and starboard speeds by entering GPS information. The ship’s port and starboard speeds at its arbitrary position can be indicated by entering ROT information. An optimal Doppler sonar system can be configured by combining a variety of options. On-line maintenance (option) allows any failure to be detected during navigation.
This equipment is designed to comply with the following standards:
IMO A.824(19) Revised MSC.96(72), IMO A.694(17), IEC61023:1999, IEC60945:2002 and IEC61162-1:2000
