What Is the Difference Between NMEA 0183 Version 1.5 and 2.0 ?

Data fields and data valid flags have been added to some of the sentences in version 2.0.
One commonly used sentence is the position sentence GLL, which has an UTC time field
and a data valid flag added at the end of the sentence.


So I'd guess this will extend into higher versions - adding of more data validity flags. You can be sure that the system will stay backwards compatible and that the sequences used for road navigation won't be adversely affected.
