[GIS] the difference $GPRMC and $GPRMCA

gpsnmea

What is the difference between $GPRMC and $GPRMCA strings?

I can find online documentation about $GPRMC strings, however I have a device that sends $GPRMCA strings.

$GPRMC,225446,A,4916.45,N,12311.12,W,000.5,054.7,191194,020.3,E*68
$GPRMCA,101959,A,0,N,0,E,0,0,20160503,,*1A

The most obvious difference is that the day field has a different formatter (YYYYMMDD in $GPRMCA instead of the DDMMYY FROM $GPRMC)

As @user30184 suggested, it's not a standard.

Apparently, it's a mix of $GPRMC and a Tetra location message.
