The JRC JLN-202 Doppler Speed Log System is a reliable marine navigation solution developed by Japan Radio Co. (JRC) for accurate measurement of vessel speed and distance. Using Doppler ultrasonic technology, the system measures speed through water (STW) with high precision, providing essential navigation information for commercial ships operating in coastal and ocean-going waters.
This complete system includes:
- NJC-202 Main Electronics Unit
- NWW-5 Remote Display
- NWW-16 Digital Display
The NJC-202 Main Electronics Unit processes Doppler signals received from the underwater transducer and calculates vessel speed and distance. The processed information is transmitted to the NWW-5 and NWW-16 display units, providing navigators with continuous speed and distance monitoring at multiple bridge locations.
The system interfaces with onboard navigation equipment including:
- Radar Systems
- ECDIS
- Autopilot Systems
- AIS
- Voyage Data Recorder (VDR)
- GPS/DGPS
- Integrated Bridge Systems (IBS)
- Navigation Repeaters
The JLN-202 is widely installed aboard:
- Cargo Ships
- Container Vessels
- Bulk Carriers
- Oil & Chemical Tankers
- LNG & LPG Carriers
- Offshore Support Vessels
- Fishing Vessels
- Passenger Ships
- Naval & Coast Guard Vessels
