LCR-100 / LCR-100N - Attitude and Heading Reference System
Culminating more than a decade of Fiber Optic Gyro (FOG) research and Micro Electro Mechanical Systems (MEMS) development, Northrop Grumman LITEF is introducing a new generation of its Attitude and Heading Reference System (AHRS) family.
The weight, volume and power consumption of this FOG AHRS are one-third that of a comparable system fitted with mechanical gyros. The system provides an excellent reliability. The LCR-100 is a direct replacement for the prior generation LCR-92 and LCR-93, providing higher performance and enhanced features.
The LCR-100 provides the data in ARINC 429 format. Optionally the attitude and heading reference data can be provided by analogue interfaces (e.g. Synchro interfaces).
Based on the high accuracy of its sensors the LCR-100 is capable of self-aligning (gyro compassing) and does not require magnetic sensors for heading alignment. The modularity of the LCR-100 also allows the integration of external or embedded GNSS. When GNSS is provided, the "hybrid" output supplies a blended position solution for navigation and flight control purposes.
Especially the LCR-100N variant is designed to continue navigation output after loss of GNSS data.
Due to it's outstanding features the LCR-100 Gyrocompass AHRS is the perfect solution for all applications whenever high performance and safety is required. In addition the LCR-100 helps to reduce the total cost of ownership.
The product is widely used in turboprops, business jets, IFR helicopters, Regional aircraft and military COTS applications. The LCR-100 is valued by airframe OEMs as a new fit solution, and also by aircraft operators as a Retrofit AHRS solution.
