GPGGA GNSS Fix Data output by GPGGA

This command is used to log time, multi-system positioning fix data of the receiver.

Output GNSS fix data using “$GPGGA”

as the message header by force. The message

begins with GPGGA.

Recommend Input:

Output 1Hz GPGGA message from current serial port:

GPGGA 1

Output 1Hz GPGGA message from com2:

GPGGA COM2 1

LOG output:

$GPGGA,025754.00,4004.74102107,N,11614.19532779,E,1,18,0.7,63.
