Abstract

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 bo 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 dead-reckoning algorithm. Conclusions, drawn from the results of the numerical experiments, show translators lead to better results, especially using SIMNET DR.
