Abstract: An embodiment of the present application discloses a global navigation satellite system (GNSS) integrated circuit (IC). The GNSS IC includes a GNSS module, a memory and a processor. The GNSS module is arranged operably to receive a to-be-identified broadcast GNSS signal. The memory is arranged operably to store a plurality of ephemeris aiding data candidates, wherein the ephemeris aiding data candidates are not provided by the GNSS module. The processor is arranged operably to determine whether the to-be-identified broadcast GNSS signal is a spoofing signal based on an ephemeris aiding data reference in the ephemeris aiding data candidates.
