Abstract

A method and a device (20) are described for compensating firing errors of a gun having a weapon barrel (10.2). Firing errors, which are caused by static gun geometry errors, which influence the position of the weapon barrel (10.2) during aiming of the weapon barrel (10.2) at aiming values, are compensated.
For this purpose, the weapon barrel (10.2) is brought into measurement positions in steps by rotation around an axis. Using suitable devices of a measurement facility, an intended value, which describes the intended position of the weapon barrel (10.2), and an actual value, which describes the actual position of the weapon barrel (10.2), are detected at each measurement position. A difference between the actual value and the intended value, defined as an error value, is then calculated. Correction values are established from multiple error values of the measurement positions and the correction values are taken into consideration during later aiming of the weapon barrel (10.2).
The method and the device (20) are used for a weapon system (10) which has a system computer (10.4) for calculating aiming values for aiming a weapon barrel (10.2) of a gun (10.1) of the weapon system (10); the system computer (10.4) has a data input (24) for data which is made available, this data being intended far the purpose of being taken into consideration during the calculation of the aiming values, in order to compensate aiming errors, which are caused by static gun geometry errors and which influence the position of the weapon barrel (10.2).
