Northrop Grumman introduces LCR-350B attitude and heading reference system

Le Bourget, France June 17, 2019

Northrop Grumman Corporation's Germany-based navigation systems subsidiary, Northrop Grumman LITEF GmbH, announced it is introducing the LCR-350B, a new Micro-Electro-Mechanical Systems (MEMS)-based Attitude and Heading Reference System (AHRS). The LCR-350B joins the product family in the civil market that includes the well-established LCR-100.

Entering into production this year, Northrop Grumman LITEF's LCR-350B AHRS provides critical navigation data to the pilot, autopilot and other key systems to help achieve required situational awareness, availability and precision.

The core of the LCR-350B consists of a high-performance, MEMS-based inertial measurement unit which has been extensively flight tested on a number of platforms and meets the stringent criteria for use on manned, unmanned, rotary and fixed wing aircraft.

The unit interfaces with the LCM-300B magnetometer, features a directional gyro mode of operation and also has a hybrid Global Navigation Satellite System (GNSS)/inertial navigation capability to provide precise flight path and velocity information as well as to bridge short term satellite navigation outages.

"The LCR-350B and LCM-300B reflect our determination to continue investing in our industry-leading technology while becoming more competitive commercially," said Eckehardt Keip, managing director, Northrop Grumman LITEF. "With the MEMS technology, we are expanding our product family and will serve new segments of the market."

The LCR-350B and LCM-300B have been selected by Airbus Helicopters for the H135, H145 and H160 aircraft.
