Product Introduction
The JRC JCY-1850 SVDR (Simplified Voyage Data Recorder) is a professional marine recording system designed to continuously collect and store critical navigational, communication, and operational data from a vessel.
Often referred to as the ship's "Black Box", the SVDR plays a crucial role in maritime safety by preserving essential information that can be used during accident investigations, incident analysis, training, and regulatory inspections.
The JCY-1850 is designed to comply with international maritime regulations and is widely installed onboard:
- Cargo Ships
- Container Vessels
- Bulk Carriers
- Oil Tankers
- Chemical Tankers
- Offshore Vessels
- Passenger Ships
- Government & Naval Vessels
What Is JRC JCY-1850 SVDR?
The JCY-1850 is a marine data recording system that automatically records operational information from various bridge and navigation equipment.
The system continuously stores:
- GPS Position
- Vessel Speed
- Gyro Heading
- Radar Information
- AIS Data
- Bridge Audio
- VHF Communication
- Alarm Status
- ECDIS Data
- Navigation Events
This information is preserved inside a protective recording capsule for future retrieval if required.
Main Features
