No fuss, self-learning module
Attitude Heading Reference System (AHRS) M&M Modules
PNI’s M&M modules will self adapt and learn its system and its environment automatically to provide accurate quaternions, heading, pitch and roll. All while using 100 times less power than traditional AHRS modules.
PNI’s M&M modules incorporates PNI’s SENtral sensor fusion coprocessor that runs PNI’s proprietary 15 state Kalman filter sensor fusion algorithms to continuously correct for gyro bias drift, automatically calibrate for hard and soft-iron and reject magnetic distortions, while consuming less than a ¼ of a milliamp.
The SENtral Coprocessor works with all available inertial sensors. M&M modules come configured with the following sensors:
- PNI M&M Amber module: PNI’s RM3100
Magnetic Sensor and ST Micro’s LSM6DSL
Accelerometer/Gyroscope and LP25H Pressure sensor. - PNI M&M Magenta module include AKM
AK09911D magnetic sensor and ST.
