Sensor Calibration

ALTA Pro features a highly sensitive 3-axis magnetometer, gyroscope, and accelerometer 
that measure specific force, angular rate, and earth’s magnetic field to infer heading and 
maintain stability. Occasionally, the sensors will require recalibration.

ALTA Pro’s compass should be regularly calibrated, especially when traveling 
between different geographic locations. For best results, it is recommended to 
perform manual compass calibrations away from ferrous objects, buildings and 
vehicles. In addition, concrete can contain steel rebar which may influence 
compass calibrations
