ARTIKUL-AV1

Direction Finder Compact UAV-Based

Direction finding, recording, technical analysis and classification of signals used in modern communication systems and data transfer system in HF, VHF, UHF and SHF ranges, as well as localization of their emitters. The last function is provided when the direction finder is installed on an unmanned helicopter.
