Short summary
UAV-based antenna measurements are of particular interest for physically large antennas, where traditional antenna measurement techniques are not applicable. Precise position information is obtained by GNSS, where the receiving GNSS antenna is a critical system component. An additional antenna groundplane may be beneficial or even required, depending on the antenna design. Appropriate groundplane configurations improved the achievable position accuracy in the majority of investigated cases.
