The MIMU-M is a MEMS-based AHRS with embedded GNSS receiver (GAHRS) for avionic applications, which combines high accuracy and reliability in a miniaturized package, and MEMS-based INS with embedded GNSS receiver (INS) for land applications, which combines high accuracy and reliability in a miniaturized package. The AHRS provides body angular rates and body linear accelerations from ITAR-free sensors while, velocities, attitude (roll, pitch) and heading are provided thanks to Kalman Filter based algorithm coupled with embedded GNSS receiver, 3-axes magnetic sensor and barometric sensor.
The output data is provided via RS422 digital interfaces to the aircraft systems and can be used with advanced digital instruments in all operational environments.
The MIMU-M system can be paired with an optional external Auxiliary Module GNSS (AMG) containing a second GNSS receiver, so to provide a dual GNSS, dual Antenna subsystem, capable of precise True Heading computation also in static conditions.
MIMU-M system is also designed to be interfaced with an external NMEA GNSS Receiver and Magnetometer.
