Product Introduction
The FURUNO DS-80 Doppler Speed Log is a professional marine navigation sensor designed to provide highly accurate vessel speed and distance information for commercial ships operating worldwide.
Using Doppler sonar technology, the DS-80 measures vessel movement relative to the seabed or water mass and continuously provides speed and distance data to onboard navigation systems.
The DS-80 is widely used onboard:
- Cargo Ships
- Bulk Carriers
- Container Ships
- Oil Tankers
- Chemical Tankers
- LNG/LPG Carriers
- Offshore Support Vessels
- Passenger Ships
The system is recognized for its reliability, precision, and long-term marine performance.
What Is FURUNO DS-80?
The DS-80 is a Doppler Speed Log system that calculates vessel speed by transmitting acoustic signals toward the seabed or water and measuring frequency changes in the reflected signals.
The system provides:
- Speed Through Water (STW)
- Speed Over Ground (SOG)
- Distance Travelled
- Navigation Data Output
- Motion Information
- Speed Input for Navigation Systems
The DS-80 continuously supplies critical speed information to other bridge systems.
The equipment can interface with:
- ECDIS
- Radar
- AIS
- Autopilot
- Voyage Data Recorder (VDR)
- Integrated Navigation Systems
