Abstract

A live virtual constructive (LVC) gateway system is configured to transparently separate, merge, and route data traffic between operator systems, live tactical Line Replaceable Unit (LRU) systems, and simulated tactical LRU systems. The LVC gateway is configured to receive LRU commands from an operator system, parse, the commands, and reconstruct the commands suitable for transmission to live or simulated tactical LRU systems. The LVC gateway is also configured to receive live and simulated status and target data from live tactical LRU and simulated tactical LRU systems, respectively, and merge the data for transmission to an operator system.

First claim

What is claimed is:

1. A live virtual constructive (LVC) gateway system, comprising:
a live line replaceable unit (LRU) transceiver configured to exchange live LRU data with at least one live tactical LRU device;
a simulated tactical LRU transceiver configured to exchange simulated LRU data with at least one simulated tactical LRU device;
an operator transceiver configured to exchange operator data with at least one operator device; and
an LVC gateway having computer software that, when executed by a computer processor, executes instructions to:
merge the live tactical LRU data and the simulated tactical LRU data in accordance with a merging ruleset to generate merged LRU data; and
transmit at least a portion of the merged LRU data to the operator device as transmitted operator data;
wherein the instruction to merge live tactical LRU data and simulated tactical LRU data comprises instructions to:

analyze the live tactical LRU data to determine a radio-frequency space (RF-space) format:
convert the simulated tactical LRU data to the determined RF-space format to generate translated simulated tactical LRU data; and
merge the translated simulated tactical LRU data with the live tactical LRU data to generate a merged RF-space stream.

2. The LVC gateway system of claim 1 , wherein the computer software, when executed by the computer processor, further executes instructions to:
filter commands from received operator data to generate live tactical LRU commands and simulated tactical LRU commands in accordance with a filtering ruleset;
transmit at least a portion of the live tactical LRU commands to the at least one live tactical LRU device; and
transmit at least a portion of the simulated tactical LRU commands to the at least one simulated tactical LRU device.

3. The LVC gateway system of claim 1 , wherein the instruction to merge live tactical LRU data and simulated tactical LRU data comprises overlaying simulated radar tracks over live radar tracks to generate a merged set of radar tracks.

4. The LVC gateway system of claim 1 , wherein the instruction to merge live tactical LRU data and simulated tactical LRU data comprises integrating a simulated audio stream with a live audio stream to generate a merged audio stream.

5. The LVC gateway system of claim 1 , wherein the instruction to merge live tactical LRU data and simulated tactical LRU data comprises blending augmented reality data with a live video stream to generate a merged video stream.

6. The LVC gateway system of claim 1 , wherein the instruction to merge live tactical LRU data and simulated tactical LRU data comprises blending 3-D models with a live video stream to generate a simulated video target stream.

7. The LVC gateway system of claim 6 , wherein the live tactical LRU transceiver receives electro-optical infra-red (EO-IR) turret video output.

8. The LVC gateway system of claim 1 , wherein the instruction to merge live tactical LRU data and simulated tactical LRU data comprises blending simulated targets with wide-area motion imagery (WAMI) imagery to generate a training data set.

9. The LVC gateway system of claim 1 , wherein the merging ruleset comprises filtering out portions of the live tactical LRU data when specified types of simulated tactical LRU data are received.

10. A method for processing data through an LVC gateway, comprising:
transmitting and receiving live tactical LRU data;
transmitting and receiving simulated tactical LRU data;
transmitting and receiving operator data using an operator device;
merging the live tactical LRU data and the simulated tactical LRU data in accordance with a merging ruleset to generate merged LRU data; and
transmitting at least a portion of the merged LRU data to the operator device as transmitted operator data:

wherein the step of merging live tactical LRU data and simulated tactical LRU data comprises:
analyzing the live tactical LRU data to determine an RF-space format;
converting the simulated tactical LRU data to the determined RF-space format to generate translated simulated tactical LRU data; and
merging the translated simulated tactical LRU data with the live tactical LRU data to generate a merged RF-space stream.

11. The method of claim 10 , further comprising:
filtering commands from the received operator data to generate live tactical LRU commands and simulated tactical LRU commands in accordance with a filtering ruleset;
transmitting at least a portion of the live LUR commands to at least one live tactical LRU device; and
transmitting at least a portion of the simulated tactical LRU commands to at least one simulated tactical LRU device.

12. The method of claim 10 , wherein the step of merging live tactical LRU data and simulated tactical LRU data comprises overlaying simulated radar tracks over live radar tracks to generate a merged radar track.

13. The method of claim 10 , wherein the step of merging live tactical LRU data and simulated tactical LRU data comprises integrating a simulated audio stream with a live audio stream to generate a merged audio stream.

14. The method of claim 10 , wherein the step of merging live tactical LRU data and simulated tactical LRU data comprises blending augmented reality data with a live video stream to generate a merged video stream.

15. The method of claim 10 , wherein the step of merging live tactical LRU data and simulated tactical LRU data comprises blending 3-D models with a live video stream to generate a simulated video target stream.

16. The method of claim 10 , wherein the step of merging live tactical LRU data and simulated tactical LRU data comprises blending simulated targets with WAMI imagery to generate a training data set.

17. The method of claim 10 , wherein the merging ruleset filters out portions of the live tactical LRU data when specified types of simulated tactical LRU data are received.

18. A live virtual constructive (LVC) gateway system, comprising:
a live line replaceable unit (LRU) transceiver configured to exchange live LRU data with at least one live tactical LRU device;
a simulated tactical LRU transceiver configured to exchange simulated LRU data with at least one simulated tactical LRU device;
an operator transceiver configured to exchange operator data with at least one operator device; and
an LVC gateway having computer software that, when executed by a computer processor, executes instructions to:
merge the live tactical LRU data and the simulated tactical LRU data in accordance with a merging ruleset to generate merged LRU data; and
transmit at least a portion of the merged LRU data to the operator device as transmitted operator data;
