Abstract
The present disclosure relates to a system (1) for measurement of antenna alignment of an array antenna system (2) used for wireless communication. The array antenna system (2) has an antenna position (A) relative a first coordinate system (18) and comprises a control unit (3) and an array antenna (4) having an antenna aperture plane (19), a certain coverage (5) and an initial array antenna orientation (B). The array antenna (4) further comprises a plurality of antenna elements (6) and at least two antenna ports (7, 8, 9, 10), each antenna port (7, 8, 9, 10) being connected to a corresponding subarray (11, 12, 13, 14), each subarray (11, 12, 13, 14) comprising at least one antenna element (6). The system (1) comprises the array antenna system (2) and an unmanned aerial vehicle (15). UAV, arranged to be deployed in the coverage (5) and comprising a UAV antenna arrangement (16) and a positioning module (17) that is adapted to provide UAV position information (C) relative the first coordinate system (18). In at least one UAV position (C), the UAV (15) is adapted to transmit a UAV signal to the array antenna (4) by means of the UAV antenna arrangement (16), the UAV signal comprising th…
