ABSTRACT The invention relates to an arrangement for determining the roll angle of a rotating projectile, shell, missile or the like as it leaves the barrel or launch tube. The projectile comprises a magnetised part (2) with a known polarisation direction, and the barrel or launch tube is provided with two pairs of windings (9, 10) mounted at the very front of the muzzle bell of the barrel in such a way that a voltage is induced in the windings when the projectile passes the mouth, and an evaluation unit (17) is designed to calculate, with the aid of the voltage signals, the roll angle position of the projectile upon firing.
