1. An inertial measurement device comprising;
- one or more sensor clusters, each sensor cluster including a plurality of micro inertial sensors to sample movement with respect to one axis of a plurality of axes; and
a summing unit to receive samples from each of said one or more sensor clusters indicative of said movement with respect to said one axis and to sum said samples for each of said one or more sensor clusters to an equivalent vector indicative of the sampled movement.

Abstract
Device and method for providing inertial indications with high accuracy using micro inertial sensors with inherent very small size and low accuracy. The device and method of the invention disclose use of the cluster of multiple micro inertial sensors to receive from the multiple sensors an equivalent single inertial indication with high accuracy based on the multiple independent indications and mathematical manipulations for averaging the plurality of single readings and for eliminating common deviations based, for example, on measurements of the deviation of the single readings.
