Global Navigation Satellite System Signal Generation Method for Wide Area Protection Against Numerous Unintentional Drones

This paper presents a method based on the global navigation satellite system (GNSS) interference signals to facilitate wide area protection against numerous unintentional drones. The defensive GNSS signals generated by a single signal generator sweep the authentic GNSS signals, and that the signal t...

To confirm the possibility of wide area protection, we investigated the signal generation method for the transition of signal tracking locks from authentic to defensive signals in situations where a signal generator cannot identify the drones’ positions.
