[time-nuts] GPS SPD field

Hi,

   Reference a Rockwell Jupiter GPS receiver.

   Does anyone know if the decimal point in the NMEA $GPRMC 'SPD'
ASCII field moves around? At rest it reports 0.000 but it is not
obvious whether this format is maintained on the move or
expands/contracts to suit. Does it keep the same precision with
the most significant digits expanding or not?


   TIA - Joe
