[ntp:questions] NMEA Jitter

Hi all,

Its time that I stop scratching my head with this issue :-D  

I have been working with ublox-Antaris Evalkit (borrowed from a friend).
This GPS receiver spits NMEA sentences, UBX (ublox binary messages)
and gives PPS. Very good...so configured NTP with NMEA driver. At times
it is observed that a shift of -1 second appears and continues for a day 
or more
before it comes back to proper time.

It is important that these GPS receivers generate NMEA sentences (at 
least one)
in sync with the PPS which makes them usable.

Comments and similar experiences ?

Venu
