Methods and equipment for identifying spoked areas containing spoked satellite signals

Abstract

This invention relates generally to methods and equipment for identifying spoofing regions containing spoofed satellite signals. Determining the boundaries of the region where satellite signals are being spoofed may involve identifying, based on the first set of Global Navigation Satellite System (GNSS) signals received at the GNSS receiver during the first time interval, at least one GNSS signal corresponding to a GNSS satellite that has undergone the first conversion. In this first transition, the first transition includes a transition from a non-forged state in which at least one GNSS signal is not identified as forged to a forged state in which at least one GNSS signal is identified as forged, or a transition from a forged state to a non-forged state. Additionally, the first position corresponding to the GNSS receiver position in the first transition can be determined.
