Abstract

The spoofing interference can mislead target receiver in reporting wrong position and time, it is a serious threat to the security of global navigation satellite system (GNSS) applications. The paper proposed an anti-spoofing method using the pseudo-range single-difference (PRSD) measurements of two receivers; the method recognizes spoofing signal by analysing the signal-in-space properties. Under the assumption that all the spoofing signals generating from the same antenna, their incident directions are same. However, the signals' incident directions are different for spoofing-free case, as they come from different satellites. Based on this difference, a spoofing decision variable is deduced. And the statistical characterization of the variable is analysed. In the last, the spoofing detection performance is evaluated by Monte-Carlo simulations. When the baseline is 2 meter long, the simulation results illustrated that if the false alarm rate is 0.01, the spoofing detection probability is up to 99%.
