The Sperry Marine Type 5016 Gyro Repeater is a high-accuracy marine heading repeater designed to display heading information transmitted from a vessel's master gyrocompass system. It provides reliable heading indication at remote locations throughout the vessel, ensuring safe navigation and maneuvering under all operating conditions. The Type 5016 series was developed as the successor to earlier Sperry repeater generations and is widely installed on merchant vessels, tankers, offshore vessels, naval ships, and passenger vessels.
Product Introduction
Modern ships require heading information at multiple bridge and operational locations. The master gyrocompass alone cannot provide visibility to all navigation personnel.
The Sperry Marine Type 5016 solves this requirement by accurately repeating heading data received from the vessel's gyrocompass system. The instrument uses a rotating compass card mechanism and advanced electronic processing to provide continuous heading indication.

The unit shown is a gimbal-mounted bearing repeater configuration commonly installed on bridge wings for taking visual bearings and assisting navigators during docking and pilotage operations.
What Is This Equipment?
A Gyro Repeater is a secondary heading display that receives heading information from the vessel's master gyrocompass.
Unlike a magnetic compass, a gyro repeater displays true heading information derived from the gyrocompass system.
The Sperry Marine Type 5016 family includes several configurations:
- Bearing Repeater (5016-CA)
- Steering Repeater (5016-CB)
- Magnetic Heading Repeater (5016-CC)
- Bulkhead Repeater (5016-CD)
Each version is designed for specific shipboard installation requirements.
Typical Shipboard Installation
These repeaters are frequently installed:
- Bridge wings
- Navigation bridge
- Steering positions
- Pilot stations
- ECDIS workstations
- Dynamic Positioning consoles
- Emergency steering stations
Main Features
The Sperry Marine Type 5016 incorporates numerous features designed for marine navigation environments.

NMEA Compatibility
Capable of receiving heading information through marine navigation networks.
Repeater System Components
Main Components
The Type 5016 system consists of several critical components:
1. Compass Card Assembly
Displays vessel heading in a full 360° format.
2. Lubber Line
Reference mark used for heading reading.
3. Gimbal Ring Assembly
Allows stable operation despite vessel motion.
4. Illumination Control Circuit
Provides brightness adjustment.
5. RS-422 Communication Interface
Receives heading information from the gyro system.
6. Internal Processor Board
Processes incoming heading data and controls card synchronization.
7. Connection Box
Provides external cable termination and system interface.
Marine Applications
The Sperry Marine Type 5016 is used in various navigation tasks:
Navigation Monitoring
Continuous heading display throughout vessel operation.
Bridge Wing Bearings
Used for visual bearing observations during coastal navigation.
Pilotage Operations
Assists pilots during harbor approach and departure.
Docking Maneuvers
Provides heading reference while berthing.
Dynamic Positioning Support
Acts as an auxiliary heading display.
Emergency Navigation
Provides heading information when bridge personnel are operating away from the master gyro display.
Common Problems & Troubleshooting
1. No Heading Display
Possible Causes
- Loss of gyro signal
- RS-422 communication failure
- Power supply interruption
Corrective Actions
- Verify gyrocompass operation
- Check interface connections
- Inspect power supply voltage
- Confirm heading data transmission
2. Heading Timeout Alarm
Symptoms
- Flashing source indicator
- Error indication active
Cause
No valid heading data is being received from the gyro source.
Solution
- Verify gyro output
- Check NMEA / RS-422 interface
- Confirm active heading source selection
3. Compass Card Not Synchronizing
Causes
- Signal interruption
- Internal synchronization fault
- Configuration issue
Solution
- Perform synchronization procedure
- Verify communication settings
- Check interface board condition
4. Illumination Failure
Causes
- Faulty dimmer circuit
- Power supply issue
- LED illumination failure
Solution
- Inspect internal lighting circuit
- Verify supply voltage
- Replace defective components
5. Incorrect Heading Display
Causes
- Wrong heading source selected
- Data protocol mismatch
- Configuration error
Solution
- Verify gyro selection
- Check baud rate settings
- Inspect system configuration parameters
Maintenance Tips
Regular maintenance ensures long-term reliability.
Daily Checks
- Verify heading accuracy
- Check display illumination
- Inspect physical condition
Weekly Checks
- Inspect cable glands
- Verify mounting hardware
- Confirm smooth gimbal movement
Monthly Checks
- Test heading synchronization
- Verify communication integrity
- Check repeater response to heading changes
Cleaning Recommendations
Use only approved non-aggressive cleaning agents. Organic solvents and acetone should never be used on the front plate.
Outdoor Installation Care
Bridge wing repeaters should be protected from excessive solar radiation when not in use.
Why Ships Still Use This Equipment
Despite the widespread adoption of integrated bridge systems and ECDIS, dedicated gyro repeaters remain essential.
Reasons include:
- Independent heading display
- Enhanced bridge safety
- Compliance with marine regulations
- Reliable operation during critical maneuvers
- Redundancy for navigation systems
- Improved situational awareness
For bridge wing operations and bearing observations, a dedicated repeater remains significantly more practical than relying solely on ECDIS displays.
Frequently Asked Questions (FAQ)
What is the purpose of a gyro repeater?
A gyro repeater displays heading information received from the vessel's master gyrocompass at remote locations.
Is the Type 5016 suitable for outdoor installation?
Yes. The bearing repeater versions are designed for exposed marine environments and provide IP56 environmental protection.
