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.
