Air Force Distributed LVC Prototype Project


Distributed LVC Prototype Project

The US Air Force uses live-virtual-constructive (LVC) training to acquire skills, develop and maintain proficiency, and rehearse mission profiles. This project will demonstrate a system that balances computer processing for modeling and simulation at the ground and aircraft processing nodes when connected by a training datalink with limited bandwidth.

The Distributed LVC prototype will consist of a ground-based computational node connected to a tactical aircraft pod-based node via a simulated radio datalink similar to the fifth-generation advanced training waveform (5G-ATW) developed by the Air Force Research Laboratory’s SLATE Advanced Technology Demonstration. The 5G-ATW datalink passes encrypted messages via compressed distributed interactive simulation (cDIS) data packets. During a training exercise, many (several hundred) simulators and computer generated forces (i.e., synthetic entities) will pass data about their performance, weapons and status through ground-based communication node(s) to many (~100) live training systems via a training radio datalink. The live training systems will also be sending data about their performance, weapons, and status to the synthetic entities. Through this data exchange, the live operators will be able to train with and against many more entities than can be reasonably fielded in an exercise hosted on a range with limited airspace, real estate, and security.

Entities generate data packets as required to communicate a change in their performance, weapons and system status. In a dynamic, air combat environment, many (~10-20) messages may be required from a single entity every second. These data are transmitted on the 5G-ATW datalink using up to 64 discrete frequencies within the upper L band. However, the transmission is subject to interference and attenuation requiring repeating messages. Therefore, in order to support a large force employment exercise with up to 1000 live and synthetic entities, a very large number of data packets must be passed between live and synthetic entities.

The Distributed LVC prototype project will demonstrate an architecture that establishes models and simulation at the ground node and aircraft node in order to reduce the data volume on a connecting training datalink.

A Request for White Papers, with an approximate 10 page or less response, is estimated to be released in mid-March.
