Question

Hi, I am using your M20048-1 GPS module.

Is there a guaranteed way to determine the GPS module has a valid date and time? Can I reliability use the "060180" to mark the date/time as invalid or is it possible the module may broadcast other dates that are invalid?

Invalid Date and Time:
$GPRMC,000526.021,V,,,,,0.00,0.00,060180,,,N*40

Valid Date and Time:

$GPRMC,115901.091,V,,,,,0.00,0.00,070320,,,N*4E

Answer 1

Hi, You need to wait until the module has acquired a fix before using the date/time on the RMC message.
