In HLA, the concept of dead reckoning (DR) is extended to attribute extrapolation. The federation can use any formula that is agreed upon by the participating federates. If a non-DIS-standard DR algorithm is chosen, a DIS-compatible simulator has to modify its software to join the federation. The cost can be significant for this kind of modification. This paper suggests the use of dead-reckoning translators to solve this problem. To assist the study, a software tool, Dead Reckoning Translator Simulation Program (DRTSP), was designed and developed. It is a MATLAB-based program using the Graphic User Interface to provide a user-friendly environment. A sample flight trajectory recorded from a flight simulator is used to test the algorithms. The output of the program is the number of PDUs (updates) and the errors of each deadreckoning algorithm. Conclusions, drawn from the results of the numerical experiments, show translators lead to better results, especially using SIMNET DR.
