摘要

Northrop Grumman's Fiber-Optic Gyro (FOG)-based family of Inertial Navigation Systems (INS) have demonstrated superb performance in applications ranging from high dynamic fighter aircraft, unmanned air vehicles, land vehicles and commercial aircraft.rnCompared to the previous generation of ring laser or mechanical gyro systems, the FOG navigation systems offer significantly smaller size, much lower weight, lower power consumption, vast improvement in life and reliability, all at the same or better level of accuracy. Using FOG technology, low noise accelerometers, high performance global positioning system, and sophisti-rncated integration algorithms, Northrop Grumman has demonstrated the FOG navigator's ability to provide extremely low-velocity noise information, enabling improved surveillance sensor compensation and reduced target location errors. Transfer alignment techniques also permit leveraging the full accuracy of the FOG navigator to smaller remote inertial measurement units used for motion compensation or stabilization of other sensors, such as radar or electro-optic pods.
