Ballistic correctable munition(BCM) is a kind of armament which can be widely developed. It worked by adding correcting module on average shells. But now it becomes a problem of the micromation of inertial guiding module, then ballistic trajectory can not be real-time detected. Only the range of cannon can be corrected while the direction cannot. This limits the shells' shooting accuracy and comsumes more shells. Micromachined gyroscope based on MEMS has smaller size and lower cost with appropriate precisio...
