Abstract
An apparatus and method for electronically controlling ordnance fuzes by sensing magnetic fields proximate the ordnance via a magnetic field sensor. The sensor is preferably a giant magnetoresistance detector. For spinning ordnance, in-flight cumulative range can be calculated by counting turns of the spinning ordnance. Ordnance may be armed a pre-determined time after exit of the ordnance from a weapon firing the ordnance as determined by the magnetic field sensor. The invention is also of a giant magnetoresistance sensor and method for making same and an apparatus for and method of sensing angular velocity for spinning ordnance.
