ROTATABLE ORIENTATION INDEPENDENT GRAVITY SENSOR AND METHODS FOR CORRECTING SYSTEMATIC ERRORS |
摘要 |
A method to correct for a systematic error of a sensor having a plurality of accelerometers configured to measure gravitational acceleration, the method including: rotating the plurality of accelerometers about a first axis; obtaining a first set of calibration measurements from the plurality of accelerometers from the rotation about the first axis; determining a first systematic error for each accelerometer in the plurality using the first set of calibration measurements; and removing the first systematic error from sensor measurements to correct for the systematic error.
