[time-nuts] Strange GPS behaviour

Hi Hal et.al,
 
as requested here are the plots I was talking about, one CSAC GPSDO one  
FireFly-IIA. The errors while in mobile mode are even worse than I remembered, 
 up to 400ns. It's clear when I turned the units to position hold mode as 
the  phase errors basically collapse at that time.

Also note that the indication of the number of tracked sats dosn't  change 
when turned into position hold mode.
 
The antenna position was horrible, most of the time only one sat was  being 
tracked directly.
 
bye,
Said

Yes.  Please  do.
