Systems and methods for calibrating triaxial accelerometers

A method for calibrating a multiple-triad triaxial accelerometer is provided. The method may include receiving accelerometer measured output from a first measurement triad and at least one additional measurement triad of the accelerometer. The method may further include aligning the output of a x, y, and z components of the first measurement triad to be substantially orthogonal with respect to each other, aligning the output of x, y, and z components of at least one additional measurement triad to be substantially orthogonal with respect to each other, and rotating the output of at least one measurement triad so the outputs of all measurement triads substantially align with each other. The method may further include storing the result of the alignment and rotation associated with at least one calibration function associated with the multiple-triad triaxial accelerometer. The alignment and rotation may be performed substantially simultaneously.
