Northrop Grumman has introduced the mk39 mod 4A ring laser ship’s inertial navigation system.

The mk39 mod 4A system is based on ring laser gyro (RLG) technology and provides the data required to make navigation decisions in a single view.

The solution will allow the operator to examine the navigator, global positioning system and the speed log by connecting a computer to any location on the ship’s network.

The mk39 mod 4A system, which can support an inertial measuring unit (IMU), also streamlines supply chain logistics.

Northrop Grumman’s Maritime Systems business unit vice-president Bill Hannon said, “We believe this smaller, lighter, more economical version of the mk39 will be a natural and effective upgrade for naval fleets.”
