GLL: Latitude, Longitude Message
$PASHS,NME,GLL,x,s
Enable/disable NMEA latitude/longitude response message on port x, where x is the
output port, and s is ON or OFF.
Example: Enable GLL message on port A
$PASHS,NME,GLL,A,ON
$PASHQ,GLL,x
The associated query command is $PASHQ,GLL,x. This command outputs the GLL
message on port x, where x is the optional output port.
Example: Output GLL message on port B
$PASHQ,GLL,B
$GPGLL
The response message is in the form:
$GPGLL,m1,c1,m2,c2,m3,c3*cc
Table 6.47 outlines the GLL structure.
If position is not valid, GLL provides: time, and position flag, for example:
$GPGLL,,,,,174645:30,V*cc
Example:
Query: $PASHQ,GLL,B [or]
Set: $PASHS,NME,GLL,C,ON
Response: $GPGLL,3722.36223,N,12159.82741,W,170003,A*7F
