Abstract
A projectile has a pair of different parts with respective orientation sensors for detecting orientation, such as the roll position of the parts. The orientation sensors may be any of a variety of sensors, such as magnetometers, light sensors, infrared (IR) sensors, or ultraviolet (UV) sensors. Orientation events of the orientation sensors, such as maxima or minima of sensor output, are determined. The orientation events of the two sensors are compared to produce an alignment correction factor for correcting for misalignment of the parts relative to one another, that is to correct for differences in alignment between the sensors of the two parts. This allows (for example) instructions produced at one of the parts to be usable at the other of the parts.
