Cost-Effective GNSS-Aided Inertial Reference System
LITEF has received ETSO certification from EASA for its LCR-110 GNSS-aided Inertial Reference System (GIRS). The certification ETSO-C201 for the AHRS functionality and – for the first time for LITEF – ETSO-C196a, allowing users to perform Required Navigation Performance procedures, for which the LCR-110 monitors the horizontal position and provides users with information on trustworthiness of the navigation data.
“This is a great achievement for the whole project team and for LITEF. Another milestone has been reached and we can now extend our product portfolio with a cost-effective inertial reference system,” commented Klaus Blatter, Product Manager Commercial Aviation.
In addition to heading, attitude and navigation data, the LCR-110 provides a navigation solution based on Kalman filtering of raw inertial and satellite navigation data, facilitating improved integrity monitoring of the GNSS information. Based on high-class inertial sensors, the device continues navigation and integrity monitoring even after the loss of GNSS information and is therefore an ideal solution for executing cost and time-optimised flight paths as part of Performance-Based Navigation with enhanced reliability, worldwide and at any time.
Its low cost and weight-saving design make it an ideal alternative to classic IRS/INS, thereby facilitating more reliable NextGen and SESAR operations of aircraft that are usually not equipped with such systems.
