Northrop Grumman’s approach moves the burden of trusted A-PNT Hub away from sole reliance on GPS to the complementary use of inertial devices augmented with additional alternative methods of navigation.
The LN-200S is a small, lightweight, highly reliable, state-of-the-art fiber-optic inertial measurement unit (IMU). The LN-200S comprises three solid-state fiber-optic gyros and three solid-state silicon Micro Electro-Mechanical Systems accelerometers in a compact package that measures velocity and angle changes in a coordinate system fixed relative to its case.
