Abstract

An area denial system may be operationally placed with communication latency compensation. The area denial system may include a plurality of munitions, one or more sensor devices, and a command and control unit, networked together and having a command and control latency for communication between the command and control unit and the remainder of the area denial system. Latency compensation may include determining a first target position, determining a first predicted position area for the target using the command and control latency and the first target position, receiving an authorization to arm one or more of the munitions, determining a second target position, and determining that the second target position is outside a threshold distance from a first authorized munition of the one or more authorized munitions, and in response, de-authorizing the first authorized munition.

Claims (50)

1.

notifying one or more human operators, via the command and control unit, of one or more recommended munitions for engaging a target based on a first target position detected by the one or more sensor devices, the notification subject to a data latency between the command and control unit and the one or more gateway devices;

receiving, from at least one of the one or more human operators via the command and control unit, authorization to fire one or more munitions of the plurality of munitions, the authorization received subject to the data latency between the command and control unit and the one or more gateway devices;

determining a second target position relative to the obstacle field, the second target position determined subsequent to receiving the authorization and latency compensated for a two-way data latency based on the data latency between the command and control unit and the one or more gateway devices; and

determining that the second target position is outside of a threshold distance from a first authorized munition of the one or more authorized munitions; and

compensating for the command and control latency by de-authorizing the first authorized munition.

2. The method of claim 1 , further comprising:

determining the one or more recommended munitions using a first predicted position area for the target, the first predicted position area indicating a range of possible locations for the target using the one or more sensor devices and the one-way data latency between the command and control unit and the one or more gateway devices; and

notifying, using the command and control unit, the one or more human operators of the first predicted position area.

3. The method of claim 2 , wherein the one or more recommended munitions are further determined by using an engagement range of each of the plurality of munitions.

4. The method of claim 1 , wherein the second target position is determined using the one or more gateway devices.

5. The method of claim 1 , wherein de-authorizing the authorized munition is executed automatically using at least one of the one or more gateway devices.

6. The method of claim 1 , wherein the second target position is determined without communication to the command and control unit.

7. The method of claim 1 , further comprising:

determining that the second target position is within a threshold distance of a second authorized munition of the one or more authorized munitions, and in response, maintaining the authorization of the second authorized munition.

8. The method of claim 1 , wherein the authorization to arm one or more munitions of the plurality of munitions is received at the one or more gateway devices.

9. The method of claim 1 , further comprising:

determining that the second target position is within a threshold distance of a second authorized munition of the one or more authorized munitions, and in response, transmitting the authorization to the second authorized munition of the one or more authorized munitions from the one or more gateway devices.

10. The method of claim 1 , wherein the data latency between the command and control unit and the one or more gateway devices is in a range between and including 0.2 seconds to 5 seconds.

11. The method of claim 1 , wherein the command and control unit is positioned away from the obstacle field a distance substantially in a range between 10 kilometers to 200 kilometers.

12. The method of claim 1 , wherein the first predicted position area for the target further indicates the range of possible locations for the target compensated for a two way data latency.

13. An area denial system for deployment in a region, the area denial system comprising:

a plurality of munitions;

one or more sensor devices;

a command and control unit; and

one or more gateway devices configured to network the plurality of munitions, the one or more sensor devices, and the command and control unit in an area denial network having a command and control latency for communication between the command and control unit and the remainder of the area denial system;

wherein the command and control unit, and the one or more gateways devices each include a processor and a computer readable storage medium communicatively connected to the processor, the computer readable storage mediums having program instructions embodied therewith, wherein each of the computer readable storage mediums is not a transitory signal per se, the program instructions executable by the respective processors to cause the respective processors to:

notify one or more human operators, via the command and control unit, of one or more recommended munitions for engaging a target based on a first target position detected by the one or more sensor devices, the notification subject to a data latency between the command and control unit and the one or more gateway devices;

receive from at least one of the one or more human operators via the command and control unit, authorization to fire one or more munitions of the plurality of munitions the authorization received subject to the data latency between the command and control unit and the one or more gateway devices;

determine a second target position relative to the obstacle field, the second target position determined subsequent to receiving the authorization and latency compensated for a two-way data latency based on the data latency between the command and control unit and the one or more gateway devices; and

determine that the second target position is outside of a threshold distance from a first authorized munition of the one or more authorized munitions; and

compensate for the command and control latency by de-authorizing the first authorized munition.

14. The system of claim 13 , wherein the program instructions are further executable to:

determine the one or more recommended munitions using a first predicted position area for the target, the first predicted position area indicating a range of possible locations for the target using the one or more sensor devices and the one-way data latency between the command and control unit and the one or more gateway devices; and

wherein the first predicted position area for the target further indicates a position for the target compensated for a two way data latency.

15. The system of claim 13 , wherein the data latency between the command and control unit and the one or more gateway devices is in a range between and including 0.2 seconds to 5 seconds.

16. The system of claim 13 , wherein:

the plurality of munitions, the one or more sensor devices, the command and control unit, the one or more gateway devices, and the target for the area denial system are represented by a design structure encoded on a second non-transitory computer readable storage medium, the design structure comprising elements that are accessible by a computing device for an area denial simulation.

17. The system of claim 16 , wherein the design structure elements comprise:

program instruction means to simulate notifying one or more human operators, via the command and control unit, of one or more recommended munitions for engaging a target based on a first target position detected by the one or more sensor devices, the notification subject to a data latency between the command and control unit and the one or more gateway devices;

program instruction means to simulate receiving from at least one of the one or more human operators via the command and control unit, authorization to fire one or more munitions of the plurality of munitions, the authorization received subject to the data latency between the command and control unit and the one or more gateway devices;
