It's a gpsd bug/quirk.  I've seen the same thing on a PC with a Venus chip 
connected via USB.

I mentioned it a month or two ago but it fell through the cracks.

My case occasionally flips from one mode to the other.  Occasionally is 
ballpark of a day.

I thought gpsd was supposed to do the right thing.

I have one.  I'm seeing a 10 microsecond pulse.  One per second.

That's from a Venus chip on a Sparkfun breakout board from 4 years ago.

These are my opinions.  I hate spam.
