Abstract

The present disclosure is directed to a training system comprising at least one real asset having real asset data, a transceiver coupled to the real asset, at least one simulator adapted to simulate an asset; and a bridge coupled between the at least one simulator and the transceiver, whereby training can be carried out using both the at least one real asset and the simulated asset in concert. The bridge uses a piecewise polynomial interpolation algorithm to transform the real asset data into the proper format for use in the simulated environment. The present disclosure is also directed to the real asset-to-simulated environment bridge itself and a method of providing a bridge between at least one real asset and a simulated environment.

Claims

1. A training system to train a user, comprising:

at least one real asset having real asset data;

a transceiver coupled to the real asset;

at least one simulator that simulates an asset to enable a user to train to use the asset; and

a bridge coupled between the at least one simulator and the transceiver that facilitates the training and transmits the real asset data to the simulator, with the simulator using the real asset data to simulate the asset to train the user.

2. The system of claim 1, wherein the bridge comprises a computer readable medium having computer readable program code embodied thereon.

3. The system of claim 2, wherein the computer readable program code comprises a piecewise polynomial interpolation algorithm.

5. The system of claim 4, wherein the computer readable code, when executed, dead reckons the real asset data and interpolates the real asset data based on the computed curves when the bridge stops receiving the real asset data.

6. The system of claim 5, wherein the computer readable code, when executed, smoothes each curve created by the bridge.

7. The system of claim 1, wherein the bridge further comprises a simulator adapted to simulate a strike target asset comprising at least one of munitions, tanks and missile launchers.

8. The system of claim 1, wherein the bridge comprises a recorder adapted to record the real asset data.

9. The system of claim 8, wherein the recorder comprises means for playing back the real asset data recorded by the recorder.

10. The system of claim 1, wherein the bridge comprises a filter adapted to restrict the flow of real asset data and simulated asset data therethrough.

11. The system of claim 1, wherein the bridge is configured to support a plurality of simulation communication protocols, and wherein the simulation communication protocols comprise at least one of a distributed interactive stimulation protocol, a high-level architecture protocol and a training enabling architecture protocol.
