Abstract: An inertial measurement system comprising at least one sensor cluster comprising a plurality of inertial sensors for sampling at least one of acceleration and angular velocity of said at least one sensor cluster with respect to each axis in a plurality of axes of a reference frame, and for producing individual outputs associated with said at least one of acceleration and angular velocity, at least three of said inertial sensors said sampling with respect to each same respective said axis; and a processing engine for receiving said individual outputs, combining said individual outputs to yield respective combined outputs, detecting which of said individual outputs diverges from at least one of their inter-comparison, and its respective combined output, according to a decision rule, said processing engine configured to dynamically self-calibrate a parameter that includes individual scale factor of those said inertial sensors whose said individual outputs were detected to diverge.
