It is difficult to debug a system that hasn't been running long enough 
to synchronise.  However, you should choose a better external source; 
155ms delay is almost an order of magnitude higher than what you should 
be getting for a reasonable source.

It might also be advisable to add a couple more external sources and to 
fudge out the static error on your NMEA input.
