Extrapolation Error of α-β Tracker for Automatic Dependent Surveillance (ADS)
Akira Ishide · The Journal of Japan Institute of Navigation · 2004
An α-β tracker will be applied to the tracking of aircraft using Automatic Dependent Surveillance (ADS). On-board GPS receivers will be used to acquire aircraft position data for ADS. We analyzed the errors of the extrapolated positions obtained by applying α-β tracking to the ADS position samples derived theoretically and from GPS-derived positions. We clarified the tracking characteristics in both straight and curved flight courses. We also clarified the effect of meandering in flight and positioning accuracy on tracking errors.
