Title (EN) GEOLOCALIZATION SYSTEM WITH SPOOFING DETECTION
(FR) SYSTÈME DE GÉOLOCALISATION AVEC DÉTECTION D'USURPATION
Abstract:
(EN) A GNSS enabled device (2) configured to process pulse per second (PPS) signals, in particular from a GNSS satellite constellation to determine a global position of the GNSS enabled device. The device comprises a GNSS receiver module (4) configured to acquire the PPS signals, a computing unit (8), and a reference timer (6) comprising a local reference clock (16) and a timer circuit (18) to measure periods of said PPS signals. The computing unit and reference timer are configured to measure a variance in jitter of said PPS signals to determine whether the received PPS signal is genuine or spoofed.
(FR) L'invention concerne un dispositif activé par GNSS (2) conçu pour traiter des signaux d'impulsion par seconde (PPS), en particulier à partir d'une constellation de satellites GNSS afin de déterminer une position globale du dispositif activé par GNSS. Le dispositif comprend un module récepteur GNSS (4) conçu pour acquérir les signaux PPS, une unité de calcul (8) et un temporisateur de référence (6) comprenant une horloge de référence locale (16) et un circuit de temporisateur (18) pour mesurer des périodes desdits signaux PPS. L'unité de calcul et le temporisateur de référence sont conçus pour mesurer une variance dans le sautillement desdits signaux PPS pour déterminer si le signal PPS reçu est authentique ou usurpé.
