Alternative to dead reckoning for model state quantisation when migrating to a quantised discrete

Abstract

Some progress has recently been made on migrating an existing distributed parallel discrete time simulator to a quantised discrete event architecture. The migration is done to increase the scale of the real-time simulations supported by the simulator. This however requires that the existing discrete time models be modified to work within the quantised discrete event environment. To this end the use of model state quantiser and quantised integrator pairs are required. An alternative to dead reckoning is suggested for the quantized integrator algorithm: a state estimation algorithm that has successfully been used to inject live aircraft into a discrete time simulator
