Nope, should be impossible. Looks to be exactly 500 milliSec apart.
Do you have a square wave output? Or a 2Hz output?
How about you put ppstest on it to see. Except on the Pi you only
see one edge, so can not tell square wave from 2 Hz. Got a scope?
What is the GPS again?

square wave is uncommon, but I have seen it.
What I have not seen is the gpsd edge detection circuitry output
2x in the same second. There is supposed to be logic to prevent it, and
it used to work.
