ABSTRACT:
A system for an unambiguous determining of the roll angle attitude of a rotating projectile, grenade, missile or the like with the aid of a polarized electromagnetic radiation, comprises a transmitter for emitting a position-determining polarized radiation (space wave) in the direction of the projectile and a receiver arranged in the projectile for receiving the emitted radiation. The emitted space wave is made up of a carrier wave reference with frequency f.sub.1 which has been phase-modulated with a modulation frequency f.sub.2, wherein f.sub.2 is<<f.sub.1 and wherein f.sub.2 forms a submultiple of the carrier wave frequency f.sub.1.
