(1) Vendor needs to provide prototype technologies design, development, integration, and deployment solution. • High frame rate real–time simulation execution. Compute systems that can execute correlated real–time flight simulations for multiple systems at very high frame rates, for example, graphics processor–based computation. • Midcourse and navigation environment emulation/simulation. Simulation/emulation and real–time projection/injection capabilities for PNT such as Global Navigation Satellite System (GNSS) and alternative PNT solutions. • Solutions shall include propagation, environmental, and countermeasure effects. • Target and background modeling systems that enable rapid model development, possibly utilizing readily available data (commercial, satellite, data collects, etc.).
