1. A method for determining a spoofing region containing spoofed satellite signals, the method comprising:
determining, based on a first set of Global Navigation Satellite System (GNSS) signals received at a 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;

determining a first location corresponding to a location at which the GNSS receiver was located during the first transition;
determining the spoofing region based at least in part on the first location; and
sending data indicating the spoofing region to a server.
