RMC data is valid at timestamp?

Using the Geochron, I need to know if lat and lon in the RMC message belongs to the time in the timestamp of the same sentence.

I couldn’t find any answer in the documentation I have available.

close enough. the measurement was probably made at S.000, the cpu chewed on the solution for 200ms, and then transmitted it (another 10ms), so your computer figures out at S.210 where you were at S.000.

Generally, a block of sentences (GGA, GLL, RMC, GSA, GSV) all come from the same observation and solution, and the NMEA protocol code just outputs bits and pieces of that navigation solution.

Thank you! Some measurements I made seem to validate your answer.
