DETECTRION is an Interference detection oriented GNSS RF Recording and Playback System able to operate in an autonomous and reliable manner in response to interferences by detecting them and recording a pre-programmed set of GNSS bands upon these events. DETECTRION is a market innovation, since currently there are no standalone products that integrate all features foreseen in this project. DETECTRION continuously monitors the GNSS RF bands for interferences and reports the detected interferences and its characteristics to the user or to a remote site according to the programmed severity criteria. In case of interference detection, DETECTRION can record the digitized multi band GNSS RF stream in order to allow further analysis, event evidence and, when needed, later playback.detecting them and recording a pre-programmed set of GNSS bands upon these events.
