GPGLL (GEOGRAPHIC POSITION-LATITUDE/LONGITUDE)
This command enables the GPGLL Geographic Position-Latitude/Longitude message
and determines the rate at which the information is transmitted. The periodic rate
field (yyyy) instructs the receiver either to output this message once (polled), or to
output this message at the indicated update rate (continuously). Once the receiver is
set to continuous output, the continuous flow can be stopped by sending a one-time
(polled) output request. The receiver will output the response one final time, and
then terminate any further message outputs. The value of the periodic rate is
retained through a power cycle only if battery backup power is applied.
If the receiver has just powered up and has yet to compute a position fix (GPS
quality indicator (q) is zero), then the time field (hhmmss.ss) will be nulled. If the
receiver is not computing a position fix sometime after the first fix (GPS quality
indicator (q) is zero), then the time field (hhmmss.ss) will be frozen.
Default mode: Disabled
