Tokyo Keiki Azimuth Circle

What is an Azimuth Circle?

An azimuth circle is an optical instrument placed at the top of a magnetic or gyrocompass. It assists the observer in obtaining correct bearings of celestial objects, terrestrial landmarks, or other vessels by means of a sighting apparatus. These bearings are essential for course correction, fixing of position, and navigation as a whole.

Tokyo Keiki, originally named Tokyo Keiki Inc., is a Japanese firm highly regarded for its marine and industrial automation products. The firm’s azimuth circles are globally recognized for their engineering accuracy, mechanical robustness, and operational dependability.

Key Features of the Tokyo Keiki Azimuth Circle

1. High-Precision Optics
The Tokyo Keiki Azimuth Circle has good-quality optical components, such as prisms and sighting vanes, which enable the user to align the target with the compass reading accurately.

2. Robust Construction:
Constructed with resistant materials such as brass and anodized aluminum, the unit is capable of withstanding harsh marine environments, including salt water and UV light exposure.

3. Gyro and Magnetic Compass Compatibility
The construction is versatile for application in both magnetic and gyro compasses, thus universal across different types of ships and navigation systems.

4. Ease of Use:
The azimuth circle is intuitive to operate. Its parts such as mirrors, adjustable vanes of sight, and port for viewing are easy to handle, allowing crew members of all levels of experience to effectively utilize it.

5. Night-Time Operation:
Fitted with lighted markings or facilities for illumination, the Tokyo Keiki Azimuth Circle can be used efficiently during night or bad-visibility situations.

Uses of the Tokyo Keiki Azimuth Circle

1. Naval Navigation:
Mainly, it’s employed on vessels for measurements of azimuths (directions) of celestial objects or landmarks, which assist in chart plotting precisely and route verification.

2. Naval and Military Operations:
Military ships tend to depend on such accurate instruments to increase situational awareness, particularly when operating in stealth or combat navigation.

3. Surveying and Mapping:
Azimuth circles are used in hydrographic surveys and ocean mapping surveys to give accurate directional references that are essential for data acquisition and processing.
