Abstract
A projectile is disclosed, comprising: a body; a fin having a magnet disposed thereon, the fin being coupled to the body, at least a portion of the fin being arranged to: (i) stay inside the body before the projectile is launched, and (ii) exit the body after the projectile is launched; a magnetic sensor disposed within the body, the magnetic sensor being arranged to detect changes in a position of the magnet relative to the magnetic sensor while the fin is exiting the body; and a data recorder disposed within the body, the data recorder being operatively coupled to the magnetic sensor, wherein the data recorder is configured to use the magnetic sensor to collect data indicating a displacement of the fin relative to the body after the projectile is launched.
