HMR3601

The HMR3601 is a μPOINT® Compass Module, 3-axis digital compass solution with a unique gyro stabilization to reduce effects of magnetic disturbances. Three magneto-resistive sensors, three MEMs accelerometers and a MEMS yaw rate gyro are combined to provide compass heading as well as pitch and roll angles. It has provisions for hard and soft-iron correction algorithms to handle magnetic distortion effects. A World Magnetic Model feature is provided to automatically add declination angle corrections for reference to true north (geographic north). The yaw rate sensor provides temporary heading backup when the magnetic sensors are disturbed by the local presence of distorted magnetic fields.
