More Information
Summary: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.
