Northrop Grumman’s Litef subsidiary in Freiburg, Germany, has been selected by Airbus Helicopters to provide the attitude heading and reference system (AHRS) for a variety of helicopter types. Based on the standard LCR-300 AHRS, the new LCR-350 system features a micro electromechanical system (MEMS) inertial measurement unit and enables a directional gyro mode that minimizes compass errors. Available for both civil and military rotary-wing platforms, the LCR-350 is expected to go into production in 2016.
