Independent surveillance broadcast — ADS-B receivers with DOA estimation
Christoph Reck, Max S. Reuther, Alexander Jasch, L.-P. Schmidt · 2011
On the one hand air traffic control (ATC) institutions consider to use ADS-B for its low cost and simplicity of ground station hardware. Aircraft positions transmitted via ADS-B are on the other hand in some cases error prone. In the proposed approach, direction of arrival (DOA) estimation is used to verify ADS-B airborne positions. The potential positioning error of ADS-B is thereby evaluated by comparing DOA estimates to DOA calculated from ADS-B references. To proof the accuracy of the applied DOA estimation sensor, an additional measurement campaign using a dedicated measurement aircraft has been conducted.
