Abstract: We proposed a new technology and method of shipboard equipment simulation, the time series information from Global Positioning System or BeiDou Navigation Satellite System was used to adjust the simulation time together with the time card, at the same time, a real-time extension for control of windows was used to implement real\|time simulation, thus, the technical problem of real\|time simulation in non real time system was solved. The practice of building simulation prototype system shows that compared with the real\|time system shipboard equipment simulation, the  method reduces research and development costs, and improves research and development efficiency.

Key words: simulation, shipboard equipment, real-time extension for control of Windows (RTX), ship to air missile
