LCR-100

Attitude and Heading Reference Systems

Based on decades of experience with fiber optic gyroscopes and the development of accelerometers based on MEMS technology, LITEF successfully established its LCR-100 Attitude Heading Reference System (AHRS) with a broad number of airborne platforms.

Heading data independent of magnetic sensors through gyrocompass capability
Attitude alignment on-ship
Hybrid GPS/Inertial navigation data
Optional synchro interface for retrofit into analogue avionics

Enables a precise representation of the flight path as well as a stable helicopter hovering during search and rescue missions

LCR-100 Details

This AHRS based on FOG technology is characterized by light weight, low volume and low power loss, combined with extremely precise sensor data. Furthermore, this system delivers outstanding reliability. The high precision of the sensors used on the LCR-100 facilitates autonomous heading alignment (gyro compassing). This completely eliminates the need to use interference-prone magnetic sensors for heading alignment. The LCR-100 can be connected to an external GPS receiver. In this case, the LCR-100 provides ’hybrid position solutions’ for navigation and flight control. In particular, the LCR-100N variant was designed to facilitate navigation, even during periods of GPS downtime. The outstanding properties of the LCR-100 Gyro Compass AHRS make this device especially well-suited to applications that require high levels of performance data and mission safety.

The LCR-100 replaces the previous LCR-92 and LCR-93 systems, with increased performance and extended capabilities. As standard, the data is output in ARINC 429 format with the option of attitude and heading reference data being output using analogue interfaces (e.g. synchro interface).

Today, the LCR-100 is used worldwide in turboprops, business jets, IFR helicopters, regional aircraft and in military COTS applications. This product is not only popular with aircraft manufacturers and operators for new installations, but also for retrofits.
