The LCR-350B is a MEMS-based AHRS (attitude and heading reference system) designed to provide the utmost in safety and reliability under even the most challenging of flight conditions. With a low-SWaP design, it outputs robust acceleration and rotation data as well as heading and attitude angles, and is ideal for a variety of fixed-wing and rotary UAV platforms.
The system can obtain heading reference from an external magnetometer, and can also output high-bandwidth and low-noise hybrid navigation data with the aid of an external GNSS source. It offers the option of switching to a free inertial heading (directional gyro) mode to allow compensation for local geographical anomalies.
The rugged AHRS is designed to provide enhanced resistance against high-frequency radiation such as radar, and withstands high levels of shock, vibration and acoustic noise. It utilizes an ARINC 429 interface and is certified in accordance with ETSO/TSO C-201 standards.
