Northrop Grumman Corporation has delivered the 500th WSN-7 ring laser gyroscope inertial navigation system (INS) to the U.S. Navy. Beginning with the first gyroscope installed on USS Utah (BB-31) in 1911, Northrop Grumman has built a reputation as an industry leader and partner with the U.S. Navy in navigation, positioning and sensing systems. Today, the AN/WSN?7 is the U.S. Navy Program of Record for INS on all surface combatants equipped with AEGIS weapons systems (Ticonderoga-class missile cruisers; Arleigh Burke-class destroyers), all Nimitz-class aircraft carriers, amongst other U.S. and allied vessels.

The AN/WSN?7A is the U.S. Navy Program of Record for all Los Angeles-class, Sea Wolf-class and Virginia-class submarines, and provides the same level of performance and accuracy as the AN/WSN?7, in a modified form factor fit for subsurface use. Northrop Grumman’s broad range of assured positioning, navigation and timing (A-PNT) systems provide precise, survivable, secure, resilient and agile solutions for sea, land, air and space.

The AN/WSN-7 from the Northrop Grumman Corp. integrates the AN/WSN-7 as a more reliable strapdown ring-laser gyro-based replacement for the old WSN-2 navigation system. The AN/WSN-7 offers accuracy of 1 nautical mile deviation over 24 hours. The AN/WSN-7 passive shipboard navigation system calculates and indicates ship’s position, attitude, heading and velocity in relation to the earth’s rotation. It senses motion, gravity, and Earth rotation, and receives externally supplied GPS updates and ship’s speed through the water.
