ADS-B以其低成本和简单的地面站硬件为空中交通管制（ATC）提供了方便的手段。在低百分比的情况下，通过ADS-B传输的飞机位置容易由于例如与机载导航系统的错误布线而出错。在所提出的方法中，到达方向（DOA）估计用于验证ADS-B机载位置。ADS-B的潜在的定位误差，从而评估比较DOA估计DOA值计算从ADS-B的参考和传感器的位置和方向。为了证明所应用的DOA估计传感器的准确性，使用专用测量飞机进行了额外的测量活动。
ADS-B provides convenient means of air traffic control (ATC) for its low cost and simple ground station hardware. In a low percentage of cases, aircraft positions transmitted via ADS-B are error prone due to e.g. faulty wiring with onboard navigation systems. 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 values calculated from ADS-B references and the sensor position and orientation. To prove the accuracy of the applied DOA estimation sensor, an additional measurement campaign using a dedicated measurement aircraft has been conducted.
