Case 3260 ABSTRACT The invention relates to an arrangement for determining the roll angle attitude of a rotating projectile, grenade, missile or the like (1) with the aid of polarised electromagnetic radiation, comprising a trans- mitter (2) arranged to emit a position-determining polarised radiation space wave (4) in the direction of the projectile and a receiver (5) arranged in the projectile for receiving the emitted radiation. The emitted space wave is made up of a carrier wave reference with frequency f1 which is phase-modulated with a modulation frequency f2, where f2 < = f1 and forms a submultiple of the carrier wave frequency f1.
