No I don't have a copy of the standard. I should have said second hand 
knowledge, as all receivers I have examined (about dozen different 
models) have zero padded the degrees and minutes parts in the NMEA 
output. Two digits for latitude degrees, three digits for longitude 
degrees and two digits for (whole) minutes. The amount of minute 
decimals varies; my first GPS outputs only two decimals, more recent 
"normal" GPSes output three and many OEM units output four decimals.
