Cross-sensitivity matrices are essential for converting three-axis accelerometer responses into specific acceleration components based on the gimbal's orientation in a gravitational field.
The uniqueness of these matrices varies depending on how the accelerometer is mounted on the gimbal, necessitating the definition of nine intrinsic parameters that can be measured or calculated from these matrices.
By comparing intrinsic parameters derived from independently measured cross-sensitivity matrices, institutions can identify and isolate differences related to alignment and measurement errors in their gimbal setups.
