GLL
Geographic position, latitude and longitude
GGA Global Positioning System fix data (includes time of posi-
tion)
ZDA
Time and date
are sent out when the Transceiver/GPS is in navigation mode. The
time in the position strings and the Time-and-date string are al-
ways the same. The spacing between each block of data is 2 sec-
onds and 0.5 seconds between GLL, GGA and ZDA strings when
they are present.
An example is:
$GPVTG,000.,T,000.,M,00.0,N,00.0,K
$GPGLL,5544.44,N,01228.64,E,121003,A
$GPGGA,121003,5544.44,N,01228.64,E,1,04,1,37,M,,M,,
$GPZDA,121003,19,02,1993,,
The following three strings: VTG, GLL and GGA are sent out when
the Transceiver/GPS is in acquisition mode and the currently
stored position is less than 24 hours old. The time indicates that
of the last known position. The course and speed are 8 second
mean values.
An example is:
$GPVTG,180.,T,180.,M,01.0,N,00.0,K
$GPGLL,5544.45,N,01228.67,E,121059,
$GPGGA,121059,5544.45,N,01228.67,E,0,00,1,23,M,,M,,
The following three strings: VTG, GLL and GGA are sent out when
the Transceiver/GPS is in acquisition mode and the currently
stored position is more than 24 hours old. The time field is empty.
The course and speed are 8 second mean values.
An example is:
$GPVTG,139.,T,139.,M,02.0,N,00.0,K
$GPGLL,5544.45,N,01228.68,E,,
$GPGGA,,5544.45,N,01228.68,E,0,00,1,0,M,,M,,
