  • the present invention relates to methods for determining a fire control solution of an artillery weapon in indirect ballistic fire to hit a target. Further objects of the invention are a fire control system for determining a fire control solution for an artillery weapon in indirect ballistic fire to hit a target and an artillery weapon system with an artillery weapon for combating a target in indirect ballistic fire.
  • a fire control equation is used which, when solved, provides a fire control solution according to which the weapon can be aimed in order to be able to engage the target.
  • a fire control system is usually used, which enables the fire control solution to be determined automatically.
  • the artillery weapon systems have one of the most important support functions in modern military conflicts. As flexible systems, they can be used both offensively and defensively. The precision of the artillery weapons of such artillery weapon systems has increased significantly in the past. Modern weapon systems, thanks to high manufacturing quality, the use of the latest ammunition and improved fire control technology, enable high hit accuracy. Above all, this makes it possible to minimize collateral damage and avoid endangering your own or allied forces.
  • artillery weapons attack a target using indirect ballistic fire.
  • the ballistic projectile is fired from the artillery weapon in the lower or upper angle group, ie with an angle increase of up to 65°, which is also referred to as vertical fire.
  • direct-firing weapons have a direct line of sight between the weapon and the target, so that the target can be seen from the weapon and directly relative to it in the coordinate system of the direct-firing weapon, such a direct line of sight does not exist with artillery weapons.
  • the target is rather obscured by visual obstacles or because of the great distance covers the curvature of the earth.
  • the term "non-line-of-sight" conditions is therefore also used.
  • the object of the present invention is therefore to increase the survivability of the artillery weapon and its operating crew, especially during a firefight in which the weapon fires on a target and is itself exposed to return fire.
  • this task is solved in that a changing weapon position of the weapon and a target position of the target are taken into account as geographic position data.
  • the fire control solution is determined taking into account the changing weapon position of the weapon and the target position of the target as geographic position data.

  • the fire control solution can be determined while the weapon is moving.
  • the preparation for indirect firing while moving can also be done in this way while moving.
  • the ability to fire indirectly while on the move can lead to a reduction in the reaction time between receiving a fire order via a guidance system and implementing the fire order as part of an adapted fire command after determining the fire control solution in combination with a minimized vulnerability of the weapon.
  • At least one absolute parameter that is independent of the relative position and/or relative location of the weapon and the target is preferably taken into account. By taking an absolute parameter into account, it is possible to take into account parameters that are independent of the relative position and/or relative orientation of the weapon and the target and that influence the fire control solution when determining the fire control solution.
  • the at least one absolute parameter can be determined in an absolute coordinate system that does not depend on the position of the weapon and/or the target, or it can be determined as a value on an absolute scale.

  • the absolute time can serve as a time standard to which reference is made when determining the other parameters that are included in the fire control equation.
  • the long distances involved in indirect ballistic fire of artillery weapons can result in significant transmission and acquisition times. Influences of acquisition and/or transmission times can be taken into account by means of the absolute time.
  • Parameters that exist at the same time but are present at different times due to the acquisition and/or transmission times can be synchronized with one another using the absolute time and used as synchronous parameters for determining the fire control solution.
  • the absolute time can be taken into account as a time stamp, in particular in decentrally organized system components for determining the parameters.

  • a fire control solution for hitting a moving target with a moving artillery weapon in indirect ballistic fire can be determined.
  • the consideration of the movement dynamics makes it possible, in addition to constant, linear movements of the weapon and/or the target, to also take into account changes in the movement speed and direction of movement of the weapon and/or the target.
