Electronic device for detecting GNSS interference, associated vehicle, method and computer program

An electronic device comprising:

• an inertial measurement unit providing navigation, measurements;
• a GNSS receiver measuring satellite position;
• a Kalman filter cyclically calculating an innovation vector by hybridization of data provided, as input to the Kalman filter, by said inertial measurement unit and by said GNSS, receiver;
• a filter processor applying at least one finite impulse response filter to each component of the innovation vector provided at each calculation cycle by said Kalman filter, wherein the filter coefficients are determined for each type of interference from a set of predetermined types of interferences and for each type of navigation phase from a set of predetermined types of navigation phases associated with a vehicle;
• and
• an interference detection module detecting interference when for Q cycles and on a number U of components of the innovation vector, Q and U each being an integer greater than or equal to one, the absolute value of the output of said filter processor, for at least one filter applied by said filter processor, is greater than a predetermined threshold.
