MEMS AHRS
The autonomous compact attitude and heading reference system (MEMS AHRS) is designed with standard COTS sensing components (MEMS) and electronic components. The use of original calibration and sensors error compensation algorithms assured the standalone attitude determination in the wide range of angular velocities. The external magnetic compass provides the heading determination.
The system is intended for use at the object where the non-certified instruments can be applied for control, guidance and stabilization.
