Abstract
A munition article is to be provided with an antenna which, by virtue of a characteristic which is uniform all around, permits interference-free reception of items of satellite navigation information, even if in the manner of an artillery projectile it is fired with spin along an elongate ballistic trajectory, so that a tail antenna with a spherical characteristic does not allow the expectation of good reception factors in relation to navigation satellites which are as high as possible above the horizon. Therefore the tip ( ) of the fuse tip ( ) of the projectile is equipped with a dipole satellite antenna which faces in the direction of flight. Connected to the dipole ( ) which is arranged concentrically with respect to the longitudinal axis ( ) of the projectile are symmetrically disposed conductor portions ( ) which rest with a close fit in recesses ( ) in the ballistic cap ( ).
