Fibre optic gyro compasses

Suitable for all types of vessels, the Navigat family of compasses are claimed to provide superior heading measurement in all kinds of dynamic conditions with compatibility to Sperry Marine CompassNet, the industry’s first networked heading management system.

“In today’s turbulent shipping markets, it is more important than ever to keep your course and have immediate access to information that could affect vessel safety,” says Sperry Marine Managing Director James Collet. “The evolution of the Navigat series of compass products demonstrates our commitment to providing the very best in robust, reliable technology to our customers around the world.”

Navigat 2500 and Navigat 3500 are based on solid-state technology with no moving parts, offering compact size and low weight. Their very high ‘mean time between failures’ of 150,000 hours and no annual maintenance means very low total cost of ownership and has enabled Sperry Marine to offer a five year warranty on new Navigat FOG units.

The units have rapid alignment time once installed and unlike HRG compasses whose performance in harsh environments can become degraded over time, Navigat FOG compasses have no moving parts and provide a higher level of long term accuracy, especially for heading, roll/pitch, rate of turn and heave.
