Abstract
An unmanned, automated aerial system is programmed to fly in a set pattern around an antenna. The antenna is supported by a structure on the ground, or attached to an aerostat, according to its operational wavelength, in order to avoid ground effects. The radiation pattern of the antenna under test is measured by an antenna onboard the aerial system. The positional data of both antennas is logged to account for any interference in the measurements due to atmospheric conditions.
