AHRS System (Merak-H1)
The Attitude and Heading Reference System (AHRS) employs fiber optic gyros (FOG) or ring laser gyros (RLG) coupled with quartz or MEMS accelerometers in a strapdown inertial architecture. Incorporating advanced navigation algorithms for real-time processing, the system delivers high-precision attitude and heading information through multiple operational modes including GNSS-aided and standalone inertial navigation. Applications include military platforms (radar, optical, acoustic, artillery), robotics, land/sea vehicles, submersibles, and industrial equipment. Key features:
1) Autonomous operation in GNSS-denied environments;
2) Output of both processed navigation data and raw inertial measurements;
3) Worldwide deployment capability;
4) High reliability design.
