Claim 14:
15. A device for determining a spoofing region containing spoofed satellite signals, the device comprising:
a GNSS receiver;
a memory; and
one or more processors communicatively coupled with the GNSS receiver and the memory, wherein the one or more processors are configured to:
determine, based on a first set of Global Navigation Satellite System (GNSS) signals received at the GNSS receiver over a first period of time, at least one GNSS signal corresponding to a GNSS satellite has experienced a first transition, wherein the first transition comprises:
a transition from a not spoofed state in which the at least one GNSS signal is not determined to be spoofed to a spoofed state in which the at least one GNSS signal is determined to be spoofed, or
a transition from the spoofed state to the not spoofed state;

determine a first location corresponding to a location at which the device was located during the first transition;
determine the spoofing region based at least in part on the first location; and
send data indicating the spoofing region to a server.
