LCR-100 FOG AHRS

The LCR-100 AHRS is a lightweight, compact and low-power attitude and heading reference system based on three-axis FOG gyros and MEMS accelerometers, featuring a true North self-aligning capability that does away with the need for magnetic sensors for heading alignment. The low-SWaP sensor can also accept data from an external GNSS receiver, providing hybrid navigational output for enhanced performance.

The highly reliable unit is ideal for meeting stringent UAV and aviation requirements, with DO-178 B Level A, DO-254 Level A and DO-160 E certifications and a rated MTBF of over 15,000 hours. It also features an easy-to-access digital failure history stored in solid-state memory to facilitate more effective maintenance.
