The invention relates to military technology, namely the technique of aiming cruise missiles, medium-range, and can be used on cruise missiles placed on mobile land-based launchers.

Currently almost all of the cruise missiles are equipped with systems final guidance, which uses as primary information sensor homing (radar, infrared, etc.). However, for a correct choice appointed to defeat the target, the missile must with a minimum error out design point for subsequent homing. One of the determining factors of the error output design point is the error of determining the initial azimuthal angle of the rocket.

The task of determining the initial azimuthal angle of the rocket decides sighting system. The method of implementation of this system depends on the accuracy of determining the initial azimuthal angle of the rocket.

Currently in wide use in schemes targeting systems of self-propelled launchers (forth - ICS) finds using route-navigation systems for topographic location and orientation (hereinafter MNST). This is especially prevalent in tanks, rocket launchers, etc. To implement such a scheme aiming first measure angular RA�approval at the exchange rate between instrument axis MSTO and the longitudinal axis of the barrel (tank), guides (for systems of volley fire), etc. In Fig.1 is a diagram of the angular misalignment in the exchange rate between the longitudinal axis MNST Sigma 30 and the longitudinal axis of the barrel self-propelled howitzers. According to the manual on MEITO Sigma-30 (paper No. NTA14/Sigma30-011, pp. 3-11), the measurement of the angle of misalignment in the exchange rate between instrument axis MNST 1 and the longitudinal axis of the barrel 2 self-propelled howitzer is carried out by means of two theodolites 3 and 4 with the optical control element (hereinafter ECE) 5, mounted on the housing MSTO and materialismus instrument axis MNST, and special tools with JCMS 6, mounted on the muzzle of the self-propelled howitzers and materialismus longitudinal axis of the muzzle. Mounting theodolites 3 and 4 perpendicular to the optical control elements 5 and 6, respectively, and then, spending autocollimation binding theodolites 3 and 4 to each other, measure the angles Ψ1and Ψ2. Using the values of Ψ1and Ψ2determine the angular misalignment ΔΨ at the exchange rate between the longitudinal axis MNST 1 and the longitudinal axis of the barrel self-propelled howitzer 2. The value of ΔΨ is stored in read only memory (hereinafter ROM) MNST 1 and subsequently used for targeting, self-propelled howitzers.

The solution to the technical nature closest to the proposed Fig�structure and therefore taken by the authors for the closest analogue.

It should be noted that the technical solution can be considered optimal in accuracy only for the tanks and rocket launchers, shells and shots which are composed of inertial navigation systems (hereinafter IRB).

As for cruise missiles, based on SLEEP and having in its composition the management system, the main element of which is an inertial navigation system, this method is rough and requires improvement.

This is due to the following circumstances.

First, the range of cruise missiles is ten times more range of the projectile, which in turn results in a proportional increase of the deviation from the plane of fire.

Secondly, self-propelled launchers with cruise missiles may have, unlike tanks, several individual missiles, the longitudinal axis which, unlike systems of volley fire, because of design features non-parallel to each other.

Thirdly, every missile, unlike unguided shells of tanks and gunfire volley fire, is composed of ince with individual values of passport data.

With the aim of increasing the accuracy and adaptation of the considered method of aiming application in rocket technology, the authors offer�Xia measurements of angular misalignment in the exchange rate between ince missiles and MNST SPU in several stages with regard to the design of the rocket, and how to install MSTO and missiles on the SPU.

The essence of the proposed method consists in measuring the angular misalignments in the exchange rate between the structural elements of the rocket and the SPU for the purpose of obtaining the total angular misalignments in the exchange rate between ince missiles and MNST SPU and the subsequent use of the results of the measurements during prelaunch processing for determining the true azimuth angle of the rocket by calculating corrections to the azimuthal angle measured MSTO.

Fig.2 shows a block diagram of the precision parameters, measurements which are needed in the manufacturing process ince, rockets and SPU. Symbols, names, measurement and storage of the parameters a1- 5shown in the table.

Fig.3, for example, one rocket out of ammunition, was appointed to conduct the shooting, schematically shows the storage of the parameters a1- 5and data communication for the transmission parameters of the a1and2and the azimuthal angle AndMNSTmeasured MSTO 4, the weapons control system (FCS) SPU 3 to calculate the initial azimuthal angle of Ajduring pre-launch.

Before pre-launch parameter a1is transmitted from the ROM ince 1 OBC 2, and thence, together with the parameter and in the MSA SPU 3. At the same time from MSTO 4 in FCS SPU 3 is transmitted to the azimuthal angle, measured MSTO 4. In the MSA SPU 3 with respect to the parameters a3- 5stored in the ROM suo SPU, are calculated:

- amendment to the azimuthal angle measured MSTO, according to the formula:

where j is the number of rocket-space;

- the azimuthal angle for each missile assigned to fire:

where j is the number of rocket-space.

Calculated by the formula (2) the azimuthal angle (Ajtransmitted in OBC 2 rockets, and then to ins 1. After running a prelaunch and launch.

This method allows for the operation of aiming for any rocket that is located on any rocket-any SPU.

To assess the accuracy of the proposed method of aiming was calculated, which showed that the total error in determining the initial azimuthal angle ince missiles satisfies requirements for missiles of this class requirements.

Thus, it can be stated that the invention makes it possible to create a fully automatic method of aiming that meet the accuracy requirements for medium-range missiles. It appears that this method can be used both in newly developed missile complexes and modernization of existing�existing missile weapon complexes.
