Gyrocompass AHRS LCR-100 LITEF

LITEF LCR-100

Low volume, low power consumption

High precision, outstanding reliability

Based on decades of experience with fibre optic gyroscopes and the development of sensors based on MEMS technology, LITEF established its LCR-100 Attitude Heading Reference System (AHRS) on the market successfully.

This AHRS based on FOG technology is characterised 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 malfunction-prone magnetic sensors for heading alignment. The LCR-100 can be connected to an external GNSS 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 a period of GNSS 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 safety.

The LITEF LCR-100 phased out the previous LCR-92 and LCR-93 systems, with its better performance data 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 LITEF 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.
