Final answer:
Gyrocompass repeaters are synchronized with the master gyrocompass, acting as extensions to display the same navigational heading information in multiple locations on a vessel for consistency and accuracy in readings. Option B is correct.
Step-by-step explanation:
Gyrocompass repeaters reproduce the indications of the master gyrocompass. They are synchronized with the master gyrocompass. These devices do not operate as standalone entities and are not independent; rather, they are directly wired or connected to the master gyrocompass system, receiving and displaying the same heading information.
This ensures that the same navigational information is accessible at multiple locations on a vessel, allowing for consistent and accurate heading readings across various stations. Unlike gyrocompass repeaters, a magnetic compass operates on different principles and is not directly connected to the gyrocompass or its repeaters.
Gyrocompass repeaters reproduce the indications of the master gyrocompass. They are synchronized with the master gyrocompass. This means that the repeaters receive the signals from the master gyrocompass and display the same information. They provide a way for multiple people to view the gyrocompass readings at different locations on a vessel or in an aircraft.
