The Sperry CN-998B/ASN-43 Gyro-Directional is a high-performance navigation system designed for applications in marine, offshore, and aviation industries. This gyro-directional navigation unit combines the functions of a gyrocompass and a directional gyro into one compact and ruggedified system, providing superior heading accuracy and reliability.
The heart of the CN-998B/ASN-43 is its advanced gyro technology, which utilizes a fine-tuned quartz gimbal-mounted gyroscope. This gyroscope continuously measures the rate of turn and the earth's rate of rotation to calculate true heading information, with an accuracy of 0.5 degrees. The gyro is housed in a ruggedized, vibration-resistant enclosure, ensuring optimal performance even in harsh marine environments.
Additionally, the CN-998B/ASN-43 is a directional gyro, meaning it can measure both heading and heading rate, making it instrumental in autopilot and stabilization systems for boats and aircraft. It provides a steadfast reference for maintaining heading or steering in automatic modes.
This gyro-directional navigation unit features a straightforward and user-friendly design. It has a high-resolution 12.1-inch liquid crystal display that provides clear and concise information on heading, course, and speed. The system can interface with multiple navigation sensors, including GPS, and can display data from multiple inputs, such as external compasses and heading sensors.
The CN-998B/ASN-43 Gyro-Directional is easy to install with a wide range of available interfaces, including NMEA 0183, NMEA 2000, and ARPINC 429. The system can also be remote-mounted, providing increased flexibility for system integration.
In summary, the Sperry CN-998B/ASN-43 Gyro-Directional is an advanced navigation system that brings together the benefits of both gyrocompass and directional gyro technology. It offers superior accuracy, reliability, flexibility, and a user-friendly interface, making it an indispensable tool for marine and aviation applications requiring precise heading information.
