摘要： Systems and methods are disclosed for detecting when a magnetic anomaly may impact the quality of data being output by a magnetometer. A plurality of detection algorithms may be performed in parallel on the sensor data. Further, indication of a anomaly from one or a combination of the detection algorithms may cause the magnetometer data to have a reduced contribution in any sensor fusion operation or may be omitted from a sensor fusion operation as desired.

摘要： Systems and devices are disclosed for calibration of gyroscope sensitivity. By comparing a reference orientation determined without gyroscope data to estimated orientations determined with gyroscope data, a calibrated sensitivity value may be derived using a known relationship between a reference orientation and estimated orientations difference and gyroscope sensitivity.

摘要翻译： 公开了用于检测磁异常何时可能影响由磁力计输出的数据的质量的系统和方法。 可以在传感器数据上并行地执行多个检测算法。 此外，从检测算法的一个或组合指示异常可导致磁力计数据在任何传感器融合操作中具有减小的贡献，或者可以根据需要从传感器融合操作中省略。
