Northrop Grumman extends partnership with Bell Helicopter to supply LCR-100 AHRS navigation systems


February 26, 2014

ANAHEIM, CA. Northrop Grumman has extended their partnership with Bell Helicopter to supply LCR-100 Attitude Heading Reference System (AHRS) flight control and navigation systems for the Bell 412 helicopter. The agreement is through 2017.

The LCR-100 AHRS, produced by Northrop Grumman’s subsidiary in Germany, has been in service since 2008 on numerous rotorcraft and fixed-wing platforms.

The LCR‑100 employs a fibre-optic gyro-based Inertial Measurement Unit (IMU) and an advanced micro-electromechanical system triad accelerometer. The unit has a high-performance directional gyro mode, which minimizes compass errors, and exceeds the Technical Standard Order/European Technical Standard Order (TSO/ETSO) C5e/f non-magnetic, gyro-stabilized drift requirement, enabling improved operation at extreme latitudes.

The LCR-100 AHRS and other Northrop Grumman products will be showcased at the HELI-EXPO 2014 in Anaheim, CA, in booth #502 Feb. 25-27.
