N2 - Regular flight inspection of navigation systems, such as instrument landing system (ILS) and the VHF omnidirectional radio range (VOR), is an important part of maintenance to ensure safe flight operations. Usually, this is done with aircraft flying and measuring at trajectories according to international recommendations from the ICAO. With the arising technology of unmanned aerial vehicles (UAVs), such flight inspections could be performed in a much more economic and efficient manner, in particular, if combined with nearfield measurement technology, allowing farfield predictions anywhere in space without limitations to particular flight trajectories. This contribution discusses an innovative approach for such nearfield inspections with UAV as research focus of the navigation aid antenna characterization—next generation (NAVANT-NG) project with corresponding requirements and first measurement results. In this contribution, both the dynamic range and the accuracy of phase measurements and stability are investigated. In particular, the accuracy and stability of phase measurements are a crucial part in such nearfield measurements. First measurement results with a test antenna and a UAV demonstrate the feasibility of proposed nearfield measurements.
