In a previous paper the authors have shown that aircraft separations needed for safety are greatly reduced if good surveillance velocity measurements are available. Unfortunately, systems which derive speed estimates from smoothed position measurements are difficult to adapt to separation assurance. They suffer greatly from offset errors when accelerations are present and for most traffic organizations, dangerous situations arise only as the result of substantial accelerations. This paper derives the optimum compromise between noise and acceleration induced errors as a function of measurement accuracy, acceleration magnitude and sampling frequency. It is concluded that better accuracy and/or greater sampling frequency than presently being recommended are required for substantial separation gains.
