AHRS System (Merak-H01)
Our high-accuracy AHRS combines optical gyro (FOG/RLG) and accelerometer (quartz/MEMS) technologies in an advanced strapdown architecture. The system delivers reliable 3D orientation data through GNSS-coupled or pure inertial modes, suitable for: • Defense platforms • Robotics and automation • Vehicle navigation • Marine systems • Precision industrial equipment.
Operational advantages:
1) Uninterrupted performance without GNSS;
2) Flexible data output options;
3) Unlimited geographical operation;
4) Continuous operation reliability.
