Abstract

The invention relates to a method for detecting spoofing of GNSS navigation signals comprising the acts of: receiving navigation signals from a first GNSS satellite and from a second GNSS satellite with a first antenna and a first receiver (S10); receiving navigation signals from the first GNSS satellite and from the second GNSS satellite with a second antenna and a second receiver (S12); measuring carrier phase differences ”(Æ)of the received navigation signals (S14); calculating phase double differences ˆ‡”(Æ) from the measured carrier phase differences ”(Æ) (S16); calculating a test statistic from all calculated phase double differences (S18); checking whether the test statistic remains in a range defined by two thresholds over a predefined time period (S20); and detecting spoofing if the test statistic remains in the range defined by the two thresholds during the predefined time period (S22).
