A projectile ( 12 ) carries a combination antenna ( 21 ), whose tuning corresponds to both the fundamental frequency of the radar ( 17 ) of a proximity fuse and the third harmonic of the carrier frequency of a satellite navigation receiver ( 20 ), in its replaceable tip ( 11 ) under its ballistic radome hood ( 14 ), so that both systems may be operated via this one combination antenna ( 21 ). For the decoupling, the radar range finder ( 18 ) is only put into operation when the navigation receiver ( 20 ) has been switched off because the projectile ( 12 ) has arrived over the target area on its corrected flight path.
