SPERRY MARINE INTRODUCES SOLID-STATE COMPASSES

Tuesday, February 18, 2020 

Northrop Grumman Sperry Marine has announced the launch of Navigat 2500 and 3500, its next generation high accuracy, maintenance-free Fibre Optic Gyro (FOG) 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, and are compatible with the Sperry Marine CompassNet 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,” said Sperry Marine MD 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 mean time between failures (MTBF) of 150,000h and zero annual maintenance requirement 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.

“Navigat FOG compasses are unique in that they can be used straight ‘out-of-the-box’ with simple installation, very short alignment time and no subsequent need for maintenance,” said Sperry Marine Product Line Manager, Compass, Speed Log and Steering Sandra Gassig. “It’s very rare that such essential navigation equipment is so easy to set up and use, meaning navigators can focus on key tasks on the bridge with confidence in their compass.”

FOG Compasses have been used in defence applications for many years, and if required, Sperry Marine will take care of export licence formalities for commercial use on the client’s behalf so compliance paperwork is kept to a minimum.
