Description

COMBAT SHOOTING SIMULATOR FOR ASSOCIATED WEAPONS

ABSOLUTE OPERATION AND RELATIVE OPERATION

FIELD Domain of the invention

The present invention relates to the field of combat fighter simulators. The present invention relates more particularly to a simulator of combat firing for weapons associating absolute operation and operation in relative terrain.

State of the art

Real Armed Combat Fire Simulators use a laser communication system to allow the shooter to make contact with the target equipped with laser detectors.

There are two system families:

• "one-way" systems where the shooter uses a noticeably divergent beam to sensitize the target who declares himself affected as soon as he detects the illumination; and "two-way" systems where the shooter has a laser that scans the space for echoes on a target and communicates distance and range of fire between the shooter and that target. The target then calculates if it is destroyed.

Simulators radio events and their location to a central system. The target receives information from the central system. The central system has the ability to destroy the geolocated targets in an area to simulate the effect of an explosive ordnance. In this case, the corresponding shooter is purely fictitious and generated by the central system. DISCLOSURE OF THE INVENTION The present invention intends to overcome the drawbacks of the prior art by proposing a method of increasing the performance of the laser simulation, in particular in the case of high-ballistic ammunition or point of impact in a non-visible zone of the shooter by adding the ability to trigger from the weapon a destruction by the central system, replacing the fictitious shooter mentioned above. The two simulation systems coexist on the same simulator allowing it, depending on the munition selected and the current flight situation to use one or the other.

To this end, the present invention relates, in its most general sense, to a method of simulating combat firing for weapons, characterized in that it implements a first laser communication simulation system to enable a firer to contacting a target equipped with laser detectors, and a second simulation system for triggering from a weapon destruction by a central system, and in that it comprises the following steps:

• acquisition of information on a weapon;

• transmission of said information to a central system;

• processing said information at said central system; · Analysis of a decision criterion to use one or the other of the two simulation systems in cohabitation;

• determination by said central system of the possible destruction of targets;

• transmission to at least one target of its new state; and in that said information includes an indication of kick start, the location of the weapon and the attitude (site, azimuth) of the weapon; said method allowing operation beyond the direct vision of the weapon shooter and / or through a building.

Thus, the method according to the present invention makes it possible to simulate combat shots for weapons by combining absolute operation and operation in relative terrain. For example, in an environment in which the target is masked by a building, a shot will be possible beyond direct vision in absolute mode through the central system using information including weapon location and attitude (site, azimuth) of the weapon.

Advantageously, said transmission is performed by radio communication.

According to one embodiment, said information comprises the location of the shooter of the weapon.

According to one embodiment, said information includes the dating of the shot.

According to one embodiment, said information comprises the angular speed of the weapon.

According to a variant, said information comprises the acceleration of the weapon.

According to one embodiment, the decision criterion for using one or the other of the two cohabitation simulation systems is the absence of laser information reaching a target following a shot actually fired.

According to one embodiment, the decision criterion for using one or the other of the two cohabitation simulation systems is the absence of a target with which to enter laser communication observed by the shooter. According to one embodiment, the decision criterion for using one or the other of the two cohabitation simulation systems is the type of weapon to which the simulator is attached. According to one embodiment, the decision criterion for using one or the other of the two simulation systems in cohabitation is the decision of the shooter.

• transmit to at least one target its new state; and in that said information comprises the location of the weapon, an indication of the start of a shot and the attitude (site, azimuth) of the weapon; said system allowing operation beyond the direct vision of the shooter of the weapon and / or through a building. According to one embodiment, said weapon is associated with a firer equipped with an attitude detection function and an inertial function constituting an extension module mechanically and electrically connected to a firing function fitted to said firer.

According to a variant, location information is generated at a firer by geolocation means.

According to one embodiment, said geolocation means are constituted by a device of GPS type.

According to another embodiment, said geolocation means are constituted by radiocommunication triangulation means.

Alternatively, location information is generated at a shooter by an indoor location device.

According to one embodiment, said weapon is associated with a shooter equipped with a complementary energy source.

Brief description of the drawings

The invention will be better understood by means of the description, given below purely for explanatory purposes, of one embodiment of the invention, with reference to the figures in which:

Figure 1 shows the different steps of the process according to the present invention; and

Figure 2 illustrates an embodiment of the present invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION Figure 1 illustrates the different steps of the method according to the present invention:

• acquisition of information on a weapon 1 1;

• transmission of said information to a central system 20; · Processing said information at said central system 20;

• determination by said central system 20 of the possible destruction of targets; and

• transmission to at least one target of its new state.

The method according to the present invention implements a first laser communication simulation system to allow a shooter to contact a target equipped with laser detectors, and a second simulation system for triggering from a weapon. 1 1 destruction by a central system 20,

The method according to the present invention also comprises a step of analyzing a decision criterion for using one or the other of the two simulation systems in cohabitation.

The decision criterion for using one or the other of the two cohabitation simulation systems can be chosen from the following group:

• lack of laser information reaching a target following a shot actually fired; The absence of a target with which to enter laser communication observed by the shooter;

• the type of weapon to which the simulator is attached;

• the decision of the shooter. Said information includes the location of the weapon 1 1, an indication of the start of a shot and the attitude (site, azimuth) of the weapon 1 1, said method allowing operation beyond the direct vision of the shooter. weapon and / or through a building.

Figure 2 illustrates an embodiment of the present invention.

In Figure 2 is shown a shooter 10 equipped with a weapon 1 1. Also shown in this Figure a building 50 comprising a ground floor and a first floor. In this building 50 are positioned three infantrymen 12 and 14 on the first floor, and a third infantryman 13 on the ground floor of building 50.

The shooter 10 and his weapon 11 communicate by radio 31 with a central system 20.

This central system 20 communicates by radio 32 with elements located within the building 50.

Figure 2 also shows a vehicle 15 (an assault tank) having a weapon 11, communicating by radio 31 with the central system 20.

In one embodiment, said central system 20 comprises a processor, a memory as well as radio communication interfaces.

In the context of the present invention, the shooter 10 is equipped with the firing function of its laser simulation system (laser transmitter) supplemented by:

- attitude detection functions (site, azimuth) on the weapon,

- and / or an inertial function on the weapon (angular velocity, acceleration), - a location function on the shooter,

- an additional source of energy if necessary.

In one embodiment of the present invention, the attitude detection functions and the inertial function are organized to form a Expansion module mechanically and electrically connected to the firing function.

In one embodiment of the present invention, the attitude detection functions and the inertial function are integrated into the firing function.

Before firing, the type of simulation is selected, according to the weapon that the user declares to want to use. If the weapon requires it, the attitude and inertial data recorded on the weapon at the time of the firing are transmitted to the central system, as well as the location of the firer 10.

The central system 20 derives from these data the point of fall of the munition and destroys the targets therein. In the example of Figure 2, information, including location on the weapon 1 1 or the shooter 10 and attitude information (site, azimuth) on the weapon, and inertial information on the type the weapon (angular velocity, acceleration) are acquired and transmitted by the radio channel 31 to the central system 20.

Then, a processing of said information is performed at said central system 20.

The central system 20 may for example determine that the targets in the south-east quarter 51 of the first floor of the building 50 are destroyed. Thus, infantrymen 12 and 14 in this part 51 of building 50 will be destroyed. Said central system 20 then communicates this information via the radio channel 32 to the elements situated in this part 51 of the building 50.

The system can be leveraged on one-way and two-way laser systems. In the case of the one-way system, the attitude and inertial information is transmitted from the casing equipping the weapon to the infantryman's equipment. Location information is generated at the infantry level by a appropriate device (GPS, indoor location, ...). The infantryman then transmits all the data to the central system.

The invention is described in the foregoing by way of example. It is understood that the skilled person is able to realize different variants of the invention without departing from the scope of the patent.
