Davidson Technologies has been active in aerospace vehicle related Modeling & Simulation (M&S) programs since the company’s inception in 1996. As aerospace technologies have matured, Davidson has emerged as a leader in the development of communications, air vehicle, system and “system of systems”-level models, specialized tools for the analysis of aerospace architectures, and custom air vehicle and communications software applications. Davidson has been active in all levels of component model development and interfaces to simulation frameworks, including system and System-of-Systems simulation and Distributed Digital Simulation (DDS). With over 100 M&S employees located at customer sites and integrated into Government and prime contractor teams, we develop many of the nation’s most complex and highest fidelity aerospace simulations.
