Hi Neil,

Thanks for the offer, and I'll start...

Is there a well-defined relationship between PPS (pulse per second) and 
any particular NMEA sentence according to the standard?  Knowing that 
relationship if there is one would be helpful in maintaining time 
synchronization during (hopefully temporary) loss of satellite contact.
