Name Description
spoofDetState
Spoofing detection state
0: Unknown or deactivated
1: No spoofing indicated
2: Spoofing indicated
3: Multiple spoofing indications
Note that the spoofing state value only reflects the dector state for the current navigation epoch. As spoofing can
be detected most easily at the transition from real signal to spoofing signal, this is also where the detector is
triggered the most. I.e. a value of 1 - No spoofing indicated does not mean that the receiver is not spoofed, it
simply states that the detector was not triggered in this epoch.
