The μAHRS is a miniature precision calibrated Attitude Heading Reference System (AHRS) featuring magnetometer, barometric pressure sensor, and L1 GPS (GNSS) receiver outputs. Measuring angular rates, linear acceleration, magnetic field, barometric altitude, and GPS WGS84 geo-position, the unit fuses IMU and magnetic field outputs to provide high-accuracy euler and quaternion attitude state estimates.
All data is GPS UTC time synchronized, and all units are fully calibrated for bias, scale factor, and cross-axis alignment, allowing for maximum sensor performance.
User-controllable I/O includes 9 GPIO, 5 Servo Outputs and 4 Analog Inputs. Output is fully configurable and available as binary or NMEA. A development kit (SDK) is available for rapid prototyping and integration into existing applications.
