The proportionality constant that relates a variation of accelerometer output to cross acceleration. This sensitivity varies with the direction of cross acceleration and is primarily due to misalignment.

Six degrees-of-freedom

The component of environmentally sensitive drift rate not correlated with acceleration. NOTE—Acceleration-insensitive drift rate includes the effects of temperature, magnetic, and other external influences.

The components of systematic drift rate correlated with the first power of a linear acceleration component, typically expressed in (°/h)/g.

An inertial sensor that measures linear or angular acceleration. Except where specifically stated, the term accelerometer refers to linear accelerometer.

Attitude and Heading Reference System

A characterization of the noise and other processes in a time series of data as a function of averaging time. It is one half the mean value of the square of the difference of adjacent time averages from a time series as a function of averaging time.

(accelerometer): The change of output (divided by the scale factor) of a linear accelerometer that is produced per unit of angular acceleration input about a specified axis, excluding the response that is due to linear acceleration. (gyro): The ratio of drift rate due to angular acceleration about a gyro axis to the angular acceleration causing it. [..]

The input signal frequency range from DC (zero frequency) up to the frequency where a -90 degree phase shift (between mechanical input and rate output) is observed.  This phase shift is determined by filters within the device.

(accelerometer): The average over a specified time of accelerometer output measured at specified operating conditions that have no correlation with input acceleration or rotation. Bias is expressed in [m/s2, g]. (gyro): The average over a specified time of gyro output measured at specified operating conditions that have no correlation with input ro [..]
