Definitions
- the invention relates to an ammunition article according to the preamble of the claim 1.
- Such an ammunition article is from WO 99/02936 A2 as a drop bomb with in Center of their tail, sandwich or patch-like satellite antenna known.
- their spherical antenna characteristics hold Contact with navigation satellites above the horizon, order through final phase control, namely by means of a comparison between the coordinates given target point and the geodetic actual position of the Ammunition item to increase hit accuracy.
- Such an antenna configuration is for ammunition articles in the form of approximately Artillery shells, however, are inappropriate. Because that from the rear antenna about symmetrical to the longitudinal axis of the projectile towards the rear oriented antenna directional pattern would be during most of the stretched ballistic Flight to the horizon, initially even below, and after the apogee only slightly over it. This makes the probability several Navigation satellites at the same time for a quick and precise determination of the path point to be able to receive sufficiently interference-free for path correction, rather low.
- the present invention is therefore the based on technical problem, one in the manner of an artillery projectile Ammunition articles were placed along a substantially horizontal trajectory to be equipped with an antenna which has a favorable directional characteristic for receiving satellite navigation information.
- the Dipole is equipped with roof capacities that reflect the effective length of the dipole extend by absorbing the current.
- the roof capacities consist of electrically conductive material, such as metallic surfaces or Wires. These conductor pieces are rotationally symmetrical about the longitudinal dipole axis arranged, which ensures the omnidirectional directional characteristic, and connected to the opposite dipole ends.
- the conventional one Dipole emitter has a half-value width of the directional diagram of 78 °.
- the dipole is in a dielectric with high Dielectric constant let in, which also reduces the Dipoles on the space available in the projectile and a Frequency range corresponding to the GPS frequencies is guaranteed.
- the ammunition item sketched in the drawing is the Tip 10 of an exchangeable detonator tip 11 of an artillery projectile under a ballistic hood 12.
- Mechanical assembly devices are not shown in detail, Impact sensor and ignition transmitter with safety devices.
- the front in the top10 is a freestanding, as an antenna for receiving Satellite navigation information for the course control of the projectile acting Dipole 13 attached so that the dipole axis concentric with the projectile longitudinal axis 14 coincides and thus an omnidirectional directional characteristic ensures.
- the dipole 13 is preferably on the frequency range of GPS frequencies Voted. To the one specified based on the desired frequencies To reduce the size of the dipole 13, the dipole 13 with roof capacities made of electrically conductive material. Their current consumption causes a virtual extension of the actual dipole.
- the roof capacities can For example, be formed from metallic surfaces or wires, at least connected to the dipole 13 at one end at an angle to the dipole axis are.
- the angle between the conductor pieces 15 and Dipole axis at the lower and upper end of the dipole 13 both the same as be different, as shown in the drawing.
- the angle at the upper end of the dipole 13 is preferably chosen so that the dipole 13 with the conductor pieces 15 can be fitted into the detonator tip 11.
- the single ones Conductor pieces 15 are attached to the dipole 13 so that they are rotationally symmetrical are arranged around the projectile longitudinal axis 14.
- the conductor pieces 15 can meandering 16 and thus the electrical path length of the short Ladder sections should be extended.
- This preferred embodiment is in the drawing representative of all conductor sections 15, for example on a conductor section 16 shown.
- the dipole 13 is equipped with two contact points 17, each of which a signal line 18 leads to the signal processing electronics (not shown).
- the Characteristics of the dipole arrangement influenced and according to the requirements can be set.
- the ballistic hood 12 consists of electrically non-conductive material, for example Plastic.
- the ballistic hood has 12 recesses on its inside 19 on the ends and dimensions of the dipole 13th or correspond to the conductor pieces 15 attached to the dipole 13. In these recesses 19 become the dipole 13 or the conductor pieces 15 at least partially form-fitting.
- the dipole 13 is in dielectric material edged and so, despite the smaller geometry, the one corresponding to the GPS frequencies Frequency range guaranteed.
- an ammunition article, the detonator tip 11 of the projectile, equipped with a dipole satellite antenna pointing in the direction of flight their completely uniform characteristics ensure interference-free reception of satellite navigation information is also possible if, according to Art of an artillery projectile under swirl along an elongated ballistic trajectory is spent.
