Anschutz Bearing Repeater Compass 133-407
Raytheon Anschütz
Refurbished
The Anschütz Bearing Repeater Compass Type 133-407 is a professional marine heading repeater designed to reproduce heading information received from a ship's gyrocompass, GPS compass or other compatible heading source.
The supplied SM MARINE SERVICE™ unit clearly shows the Anschütz Bearing Repeater Compass marking, a full 360° analogue compass card, fixed outer bearing scale and central bearing-sight mounting point.
Anschütz's official documentation confirms that the Type 133-407 displays ship heading both analogue on the compass card and digitally on the integrated display.
Manufacturer: Anschütz GmbH / Raytheon Anschütz heritage
Country of Origin: Germany
Model / Type: 133-407
Product Type: Bearing Repeater Compass / Gyrocompass Repeater
Marine Application: Remote true-heading indication and visual bearing measurement
Display Type: 360° analogue compass card + digital heading display
Ingress Protection: IP56
Heading Sources: Gyrocompass, magnetic compass or satellite/GPS compass depending on system configuration
The 133-407 is installed at bridge wings, steering positions or other navigational locations where officers require local heading information away from the main gyrocompass.
Its rotating compass card follows the vessel's heading source, while the fixed outer scale allows relative bearings to be taken. A bearing sight can be installed on the central adapter for visual bearing measurements.
Anschütz states that the repeater can accept heading from gyro, magnetic or satellite compass sources, and the corresponding source can also be indicated.
• 360° compass card
• 150 mm compass card
• Analogue heading indication
• Digital heading display
• Heading-source indication
• Fixed outer 360° relative-bearing scale
• Central adapter for bearing sight
• Adjustable illumination / dimmer
• Automatic interface recognition
• IEC 61162-1/2 NMEA interface support
• 180° offset function for double-ended ferries
• IP56 enclosure
• Designed for exposed marine bridge environments
The manufacturer specifically lists analogue/digital indication, source indication, dimmer control and a 180° offset function among the key features.
According to the Anschütz operator/service documentation:
Height: 170 mm
Width: 254 mm
Depth: 246 mm
Weight: Approx. 9 kg
Protection Class: IP56
Supply Voltage: 18–32 VDC
Power Consumption: Maximum 10 W
Operating Temperature: -25°C to +70°C
Compass Card Resolution: 0.0375°
Interface: IEC 61162-1/2 compatible serial heading interface
These specifications come from the official Type 133-407 documentation.
The repeater receives heading information electronically from the vessel's main heading source.
After power-up, the unit recognizes an IEC 61162/NMEA-compatible interface and synchronizes its heading indication automatically.
The heading is then shown in two forms:
Analogue: rotating 360° compass card
Digital: electronic heading display
This dual presentation allows both quick visual recognition and precise heading reading.
The 133-407 is more than a simple heading repeater.
The outer bezel includes a fixed 360° hull-referenced graduation for taking relative bearings. A bearing sight can be mounted on the central adapter to observe objects and determine their bearing relative to the vessel.
This makes the unit particularly useful on bridge wings and open navigation positions.
A typical Anschütz 133-407 assembly may include:
• Bearing Repeater Compass complete unit
• 360° compass card
• Digital heading display
• Bearing Repeater PCB
• Outer bearing bezel
• Lubber line
• Central bearing-sight adapter
• Pushbutton / configuration control
• Illumination components
• Power/interface electronics
• Connection cable
• Optional mounting bracket
• Optional bearing sight
Published parts references also show Bracket 142-039 and Bearing Sight CP 190 as associated accessories for some installations.
The Anschütz 133-407 can be installed aboard:
• Cargo Ships
• Bulk Carriers
• Container Ships
• Oil & Chemical Tankers
• LNG/LPG Carriers
• Passenger Ships
• Offshore Vessels
• Research Vessels
• Merchant Ships
• Double-ended ferries
• Other vessels fitted with compatible heading systems
Common installation positions include bridge wings, main bridge consoles and additional steering/navigation stations.
The 133-407 can be integrated with compatible heading-distribution systems through its electrical interface.
It is frequently associated in marine installations with Anschütz gyrocompass families such as:
STANDARD 20
STANDARD 22
STANDARD 22 NX
Third-party marine references also document the 133-407 as a repeater used with these Anschütz gyrocompass families.
Compatibility should nevertheless be confirmed from the vessel's actual interface, voltage and heading-signal configuration before replacement.
Check supply voltage, cable connections, heading-source output and the repeater's NMEA/IEC 61162 interface.
The official system includes a correction function that allows the card indication to be aligned with the digital heading value. Persistent disagreement may indicate an internal drive, PCB or synchronization problem.
Inspect internal card-drive electronics, mechanical movement and Bearing Repeater PCB connections.
Compare the indication against the main gyrocompass. Verify input source, configuration, interface format and any active offset setting.
Check dimmer setting, illumination circuitry, supply and internal connections.
Inspect interface wiring, polarity, telegram format and heading-source output.
The repeater normally detects its IEC 61162 interface automatically after power-up. If synchronization does not occur, verify the heading telegram and communication wiring.
The digital display can indicate operating states and alarms.
The official operator manual contains a dedicated overview of possible alarm indications. Exact alarm messages should therefore be diagnosed against the relevant manual rather than assumed.
• Compare repeater heading with the main gyro regularly.
• Check digital and analogue indications for agreement.
• Inspect the compass card for smooth movement.
• Check illumination and dimmer operation.
• Inspect cable glands and connections for corrosion.
• Keep the bearing-sight mounting point clean.
• Inspect bridge-wing units for water ingress.
• Check NMEA/IEC 61162 heading communication when unstable operation occurs.
• Do not force the compass card mechanically.
• Follow the official service procedure before opening or adjusting internal components.

For an existing bridge installation, replacing the 133-407 repeater alone can often be easier than altering the complete gyro heading-distribution system.
The 133-407 combines three useful bridge functions in one robust unit:
Heading Repeater + Digital Heading Display + Bearing Compass
Its IP56 construction, clear analogue card and direct bearing capability make it especially practical for bridge-wing use.
Anschütz also continues to list the Bearing Repeater Compass in its current repeater-compass product information, demonstrating the longevity of this equipment concept.
