METHOD AND DEVICE FOR DETECTING SATELLITE SIGNAL SPOOFING

A method comprising steps of: performing spatial filtering (104, 204) causing an attenuation of power of radio signals received by an antenna system in an angular sector (A); detecting (106, 206, 210) that a radio signal is received by the antenna system while the angular sector (A) includes a direc...

Zusammenfassung:	A method comprising steps of: performing spatial filtering (104, 204) causing an attenuation of power of radio signals received by an antenna system in an angular sector (A); detecting (106, 206, 210) that a radio signal is received by the antenna system while the angular sector (A) includes a direction pointing at a satellite (S1) forming part of a constellation of positioning satellites, that the received radio signal is not subject to the attenuation caused by the spatial filtering, and that the received radio signal is in the form of a positioning signal emanating from the satellite (S1); and, following the detection, implementing processing (112, 114, 212, 214) under the assumption that the antenna system has fallen victim to decoying.
