Sperry Marine NAVIKNOT Speed Log System - KDU World

In contemporary shipping practices, precise quantification of vessel speed and motion is no longer a mere navigational convenience but an element of operational effectiveness, safety, and regulatory adherence. Ensuring accurate docking maneuvers and fuel optimization processes to aid enhanced AI-driven navigation systems and autonomous vessels, reliable speed data is a necessity. The NAVIKNOT Speed Log System by Sperry Marine is a solution to these needs, since it offers a high-precision and multi-sensor solution that can serve a diverse range of ships, from luxury yachts to large commercial carriers, and make marine operations safer, smarter, and efficient.

The NAVIKNOT Speed Log System is a family of instruments used to compute Speed Through Water (STW) and Speed Over Ground (SOG). Designed by a renowned marine navigation company, Sperry Marine, the NAVIKNOT series represents a range of models appropriate for most ships and operating situations.

The NAVIKNOT series utilizes new technology to ensure reliability and accuracy in different maritime operations. Its modular design allows it to accommodate various sensors and configurations, making it highly versatile for different classes of vessels.

Multi-Sensor Technology
The NAVIKNOT system employs a combination of sensor technologies to offer accurate speed measurement:

• Electromagnetic (EM) Sensors: Calculate speed over water by detecting the variation in the magnetic field as the vessel travels.
• Doppler Transducers: The Doppler effect is used to measure speed over water by detecting frequency shifts in sound waves reflected from the water’s surface.
• Satellite (GPS) Sensors: Measure speed over ground from GPS signal processing, offering high-accuracy location.

High Accuracy
With ±1% or 0.1 knot speed accuracy, the NAVIKNOT system ensures precision, which is crucial during docking and navigation.

Two-Axis Measurement
The latest models, like the NAVIKNOT 600 series, have two-axis reading, measuring along the length and width for speeds. This proves useful for docking operations, providing broad speed information.

Intuitive Display
The system boasts a large color TFT display, which provides unambiguous distance and speed readings. It has both day and night modes, a mile counter, and the capability to perform docking maneuvers by presenting the necessary information.

Simple Installation and Integration
It is easy to install and integrate with installed vessel navigation and bridge systems with low downtime for retrofits.

Broad Vessel Compatibility
From pleasure boats to oil tankers, the NAVIKNOT system can be applied to a broad range of ships, presenting a generic solution for all types of maritime operations.

NAVIKNOT systems are not only essential for navigation but also crucial for other marine operations. They are accountable for safety, improving efficiency, and introducing new technologies for intelligent maritime administration.
