Northrop Grumman Sperry Marine

Navigat X MK1

Grumman Sperry Marine's NAVIGAT X MK 1 is a new-generation advanced marine gyro compass system that meets modern navigation and ship control technology demands.

The NAVIGAT X MK 1 Gyro Compass is the first of its type to be designed as a single unit and can be installed on any bridge on any vessel.

North stabilisation during short power failures

With more than 100 years of experience in the marine gyro compass industry, Northrop Grumman Sperry Marine delivers an advanced low weight marine gyrocompass. The unique method of supporting the system by means of mere buoyancy, ensures north stabilisation during short power failures.

The Gyro Compass from Northrop Grumman Sperry Marine ensures high accuracy and maximum reliability under all environmental conditions. The Gyro Compass uses a data transmission technology instead of using slip rings. Providing proven technology and long maintenance periods, the Gyro Compass is a long-time secure investment, with low operation costs.

Extreme weather conditions

The NAVIGAT X MK 1 Mod 7 marine gyro compass provides highly accurate heading information in extremely heavy seas. The system is equipped with a special gyrosphere container, with a unique centering pin retaining arrangement that is mounted in an additional gimbal system. This allows an almost unlimited freedom of roll and pitch (±90°).
