Northrop Grumman Corporation secured a US Navy contract for the new AN/WSN-12 Inertial Sensor Module, which is expected to enhance maritime navigation amidst GPS challenges.

The new AN/WSN-12 Inertial Sensor Module (ISM) is poised to improve the navigational capabilities of surface ships and submarines in Global Positioning System (GPS) denied environments.

The AN/WSN-12 Inertial Sensor Module (ISM) is deployed within the US Navy’s AN/WSN-12 Inertial Navigator System (INS) and is set to replace the long-standing AN/WSN-7 INS on almost every Navy vessel after more than two decades of service.

According to the company, ISM offers precise positioning data even in GPS-denied environments, thereby establishing essential Assured Position, Navigation, and Timing (A-PNT) maritime solutions.

“The new AN/WSN-12 Inertial Navigator System will deliver more precision and performance for the warfighter while occupying the same footprint as its predecessor,” said Todd Leavitt, vice president, naval and oceanic systems, Northrop Grumman. “This allows upgrades to be made on existing systems where space is at a premium.”

The first ISM will be fielded later this year, Northrop Grumman said.

In addition to their advancements in maritime navigation sensor technology, Northrop Grumman is actively engaged in developing other defense innovations for the US Navy, including modifications and upgrades to the E-6B Mercury aircraft.
