Advanced Sensor Technology
The NAVIKNOT range includes single and dual-axis speed logs equipped with advanced sensors. The Electromagnetic Sensor utilises a magnetic field generated by a coil and measures the electrical field induced by the vessel’s movement through water. The Doppler Transducer employs the Doppler frequency shift to accurately measure the vessel’s speed through water using sound pulses. And the Satellite Sensor leverages GPS technology to determine longitudinal and transverse ground speeds with high precision.
These sensors integrate seamlessly with the NAVIKNOT system, ensuring that speed data is not only accurate but also comprehensively covers all aspects of the vessel’s movement.
Comprehensive Maritime Solution
The NAVIKNOT series stands out for its comprehensive approach to speed measurement. By combining different sensor technologies, it provides a holistic view of a vessel's speed dynamics, making it an indispensable tool for modern maritime operations.
Connect and Control
Fully integrated into Sperry Marine’s CompassNet Heading Management System, the NAVIKNOT enhances operational safety and efficiency by providing a scalable platform that supports a wide range of additional sensors. This integration allows for expanded functionality and improved responsiveness in dynamic marine settings.
The NAVIKNOT series is a testament to Sperry Marine’s commitment to innovation and excellence in maritime navigation solutions. With its robust design and advanced features, it sets a new standard for speed log technology, ensuring that mariners have access to precise and reliable speed data whenever they need it.
