PATENT CLAIM also with the friction, the inclination of the location, etc. It is aiming at a firearm, with an observer, therefore difficult and often impossible, the servo units of the telescopic sight (14) and an electro-optical distance weapon and the optics dynamically in relation to each other rather (20), which is aligned parallel to the firearm (19), bring and coordinate so that their movements are identically characterized by the fact that they provide means for coordinating the? and are opposite to each other. In the above-mentioned US-PS command signal for the range measurement with at least it is shown how the observation telescope and the weapon have a signal that can control information about the deviation in relation to one another in such a way that the observation weapon (19) moves from the observation line of the The observation telescope remains aimed at the target at all times, that is, it also delivers a spy telescope (14), so that the distance measurement only takes place when the weapon is aligned. The difficulty therefore occurs when the signal provides the information that the possible movements of the weapon system, such as the deviation, are at least approximately zero. e.g. of armored vehicles that have the least possible impact on the orientation of the weapon.

If, on the other hand, the latter can be seen in accordance with 2, an optical 25 is arranged for the alignment of the barrel, the range finder is aligned by the same amount of aiming device and an optical observation line as the dynamic error of the weapon. Weapons of this type also have means of taking them into account. When the removal seeker makes a measurement, weapon ballistics, e.g. a fire control device, and a range - of course himself and the barrel of the firearm at the target seeker will also be aimed at determining the target range, which in this case is usually

Some methods for coordinating the observation, which, in the static case, are then parallel to the telescope with the range finder are already known and are dependent on the equipment of the Weapon, on the other hand, is often desired that the line of sight be complete from the fire control, etc. With such target-independent devices to maintain alignment, the line of sight is usually through, particularly in difficult terrain

US Pat. No. 3,766,827 describes a method for controlling that which is connected to a summing device 4. The latter telescopic sight of a weapon described that an observation controls the monitoring unit of the weapon 19, which has a line that is independent in relation to the weapon. In this engine 16 and a gyro 6 has. The integrator 3 is thus trapped, the line of sight of the telescopic sight is always aligned in a line 5, the control measure of the lead angle from the same direction, specifically regardless of 60 computers 17 and via a line 7, the voltage from the gyro 6 changes in influences and sizes, which affects the direction which the instantaneous angular velocity of the flows. Weapon 19 represents. On the output line 8 of the integrator 3

In many cases, and this often applies as a rule, the signal for the sum of the two delivered appears

Servo units for the alignment of the weapon relative control mass minus the instantaneous speed (which is slow, since the loading is not only done with the weapon itself-instantaneous speed) of the weapon 19, i.e. for men, but often the full weapon with its deflection angle. By means of this circuit, the speed-full weight has to be moved, as it is controlled in a known manner, for example when the weapon 19 is in armored vehicles. The loading changes due to the sum of the control speed which the operator

voltage by the operator, and the degree of the lead angle. However, it should be emphasized that the observation line remains independent, which is explained in more detail below.

The optical section of the target device has a second motor 12 and an angle-indicating component 13, which suitably contains a potentiometer, and an observation telescope 14. The servo is controlled by the computer 17 by means of the reservation angle via a line 10, the lead angle being the deflection angle is added by line 8. The addition takes place in a second summing device 9, which controls the second motor 12. A signal from the potentiometer 13, which represents the rotation of the observation telescope 14 in relation to the weapon 19, is also fed to the summing device 9 via a line 11. This signal is intended to compensate for the sum of the signals on lines 8, 10.

It can be seen from the above that the sum of these two signals represents the desired position of the observation line in relation to the current angular position of the weapon 19. With regard to the target (on the terrain), the observation line is therefore only dependent on the desired position of the observation telescope 14. This completely defines the principle of the independent observation line.

The deflection angle on line 8 is also fed to a device 18. Due to the fact that the deflection or error signal is close to zero and that in some cases the same also applies to its extent, the device 18 provides a logic output which determines when the firearm 19 can be fired.

In order to compensate for the delay in firing in some cases, it is of great advantage to predict the timing of the firing using the speed component of the deflection signal. A block 22 indicates the addition of the rotation of the observation telescope 14 in relation to the tower and the rotation of the tower in relation to the underground. This provides the angular position of the observation telescope 14 with respect to the ground, i.e. the goal.

The range finder 20 is located close to the barrel of the weapon 19, from a mechanical point of view, in a fixed position with respect to the barrel. A range finder 20 supplies signals to the computer 17 which depend on the distance from the weapon 19 to the target to which the range finder 20 is aimed. The computer 17 or the operator delivers a command signal via a line 23 for triggering the distance measurement.

The weapon 19 and consequently the range finder 20 are during a certain portion of the alignment

moments are not aimed at the same target as the observation telescope 14. However, the goal to which the latter is directed is the goal of interest, and hence the distance to that goal must be measured. Therefore, a circuit 21 is present between the computer 17 and the range finder 20, which stops or delays the command signal on the line 23 for triggering the range measurement until the range finder 20 is aligned with the same target as the observation telescope 14.

In the drawing, it has been assumed that the control coordinate shown applies to the lateral movement of the weapon 19. The observation telescope 14 is intended to be attached to the turret in which the firearm 19 and the range finder 20 are attached. In order to move the firearm 19 laterally, the entire turret must be rotated and consequently also the observation telescope 14. The latter can be rotated laterally with respect to the turret. In the case of height adjustment, it is generally known that the observation telescope 14 is mechanically coupled to the barrel of the firearm 19 by means of rods, so that the observation telescope 14 is raised and lowered together with this barrel.

However, the observation telescope 14 should also be freely adjustable in height in this case with respect to the tube. In this case, block 22 indicates that the height adjustment of the observation telescope 14 is carried out in relation to the tube, and thus also in relation to the range finder 20.

In the illustrated embodiment, the signal on line 11 can also be used to block the command signal on line 23 for range finder 20. This determines the extent to which there is an angular difference between the alignment of the range finder 20 and the alignment of the weapon 19 in the direction of the target. The signal on line 11 is therefore also supplied to block 21. If this signal is zero, it means that the observation telescope 14 is aligned parallel to the weapon 19 for the coordinate in question, so that a distance measurement can therefore be carried out. As a result, in these cases, when an extension is made that is valid for both control coordinates, a signal is taken from these elements indicating the orientation of the observation telescope 14 with respect to the weapon 19 laterally and vertically. Within a certain tolerance range, therefore, both signals should have values that indicate that the observation telescope 14 is oriented laterally and in height relative to the weapon 19. Only when this is the case should the command signal on line 23 be able to advance through block 21 to range finder 20. In a modification, this command signal is stored in block 21 until this condition is met.
