This new product is an evolution from the very successful Fiber Optic Gyro based systems. The LCR-300 AHRS offers state of the art MEMS gyro and accelerometer technology from Northrop Grumman LITEF. This small and very reliable AHRS benefits from years of experience in strap down systems. Exhaustive research and development has culminated in a product that delivers value to the operator due to light weight, small dimensions, precision output and unmatched performance.

This performance is based on unlimited range and better accuracy over the entire operating spectrum, combined with precise outputs of basic attitude and heading data, body rates and body accelerations as well as air data. The LCR-300 provides an attractive solution for a broad range of aircraft, from small to large sized airplanes and helicopters.

The LCR-300 ADAHRS version provides an embedded Air Data Computer in addition to the AHRS function. This action brings installation and weight dividend by combining two critical functions into one LRU. The vibrating cylinder sensor technology used in the ADC provides superior stability over years. It is this stability which reduces the cost of maintenance activities and hence cost of ownership of the Air Data Computer.

Long term heading reference is provided by an external Magnetometer. If available, the unit can also accept GNSS data for enhanced performance and to provide hybrid navigation data with high bandwidth and low noise. The signals are output to the cockpit system on an ARINC 429 high speed data bus. Free inertial heading or DG Mode is available to the pilots via cockpit selection.

The envisaged certifications for the LCR-300 and the LCR-300 ADAHRS are ETSO/TSO C-201 and ETSO/TSO C-106 (Air Data Option).
