Title: Apparatus and method for automated feedback and dynamic correction of a weapon system.
Abstract: A method, apparatus, and system for adjusting a targeting solution of a weapon system are provided. The weapon system may fire a projectile at a target, where the projectile comprises a location device. The location device may be active or passive. A location notification is received about the first projectile. An impact location of the projectile is determined based on the location notification. The targeting solution of the weapon system is adjusted based on the determined first impact location. The targeting solution may be adjusted directly or indirectly. An indirect adjustment of the targeting solution may include displaying a projectile-status display and/or providing a suggested targeting solution. ...

FIELD OF THE INVENTION

This invention relates to targeting of the weapon systems generally, and specifically to adjusting targeting solutions of weapon systems based on location notifications about projectiles fired by weapon systems.

BACKGROUND

Weapon systems, such as mortars and artillery pieces, are widely used by military forces worldwide. The weapon systems are used to fire projectiles, such as artillery shells or mortar rounds, at a target. Once fired, the projectile flies toward the target and lands at an impact location. The projectile may carry a payload designed to explode upon impact. Upon impact, the projectile may use concussive and explosive forces to further injure and/or destroy the target. Some projectiles also carry fragments of metal, ceramic or other materials to injure or destroy the target. The projectile may destroy the target if the impact location of the projectile is within a “lethal radius”, or close enough to destroy the target. The projectile may injure or partially destroy the target, such as when the target is near, but not within, the lethal radius.

There are many reasons to reduce the number of targeting adjustments and therefore the number of projectiles fired at the target. Current weapon systems, though generally accurate, require targeting adjustments to land projectiles within the lethal radius of the target. To verify a targeting adjustment is accurate, at least one projectile must be fired at the target. Firing projectiles may be expensive, as each projectile may cost hundreds or even thousands of dollars. Further, firing even one projectile from a weapon system may damage people and property not at the targeted location. The location of a weapon system may be given away after firing a projectile, possibly leading to an attack, such as counter-battery fire, that harms or kills the users of the weapon system as well as the weapon system.

SUMMARY

Embodiments of the present application include methods and apparatus for adjusting a targeting solution of a weapon system using location notifications received about projectiles fired by the weapon system.

A first embodiment of the invention provides a method for adjusting a targeting solution of a weapon system. The weapon system fires a first projectile at a target. A first location notification is received about the first projectile. The first projectile includes a location device. A first impact location of the first projectile is determined based on the first location notification. The targeting solution of the weapon system is adjusted based on the determined first impact location.

A second embodiment of the invention provides a projectile-tracking device. The projectile-tracking device includes a processor, data storage, and machine-language instructions stored in the data storage. The machine-language instructions are executable by the processor to perform functions including: (i) determining a first target of a first weapon system, (ii) receiving a location notification from a projectile fired from the first weapon system, (iii) determining a first impact location of the projectile, and (iv) determining a second target of the first weapon system based on the first impact location.

A third embodiment of the invention provides a system. The system includes a weapon system and a projectile-tracking device. The weapon system is configured to fire a projectile at a target. The projectile includes a location device. The projectile is configured to send a location notification. The projectile-tracking device is configured to (i) receive the location notification and (ii) display a projectile-status display. The projectile-status display includes: the location of the projectile based on the received location notification, a location of the weapon system, and the target of the weapon system.

BRIEF DESCRIPTION OF THE DRAWINGS

Various examples of embodiments are described herein with reference to the following drawings, wherein like numerals denote like entities, in which:

FIGS. 1A and 1B are block diagrams of a side view and a top view, respectively, of an example of a weapon system, in accordance with embodiments of the invention;

FIG. 2 is a depiction of an example weapon system firing a projectile at a target, in accordance with embodiments of the invention;

FIG. 3 shows an example of a projectile, in accordance with embodiments of the invention;

FIG. 4 shows an example scenario with a projectile-tracking device tracking a plurality of the projectiles fired by a plurality of the weapon systems at a plurality of targets, in accordance with embodiments of the invention;

FIG. 5 shows an example projectile-status display of a projectile-tracking device, in accordance with embodiments of the invention;

FIG. 6 is a block diagram of an example computing device, in accordance with embodiments of the invention;

FIG. 7 is a schematic view of an example location notification, in accordance with embodiments of the invention; and

FIG. 8 is a flowchart of an example method, in accordance with embodiments of the invention.

DETAILED DESCRIPTION

The instant application describes use of location notifications received about projectiles to adjust a targeting solution of a weapon system. A location notification is an indication of a location of the projectile after being fired from the weapon system. A location notification may indicate an in-flight location or an impact location of the projectile. An in-flight location of a projectile is a location of the projectile between the time when the flight of the projectile begins (e.g., when the projectile is fired) and the time when the flight of the projectile ends (e.g., when the projectile lands). An impact location of a projectile is a location where the flight of the projectile ends. One or more location notifications may be received by a projectile-tracking device about an in-flight location and/or an impact location of the projectile.
