NMEA-0183 Format
Set message output rate:
$PMOTG, RMC, yyyy*CC<CR><LF>
where:
yyyy = update rate 0000 .. 9999 seconds
CC = optional checksum
Note - the asterisk (*) is not present unless the optional checksum is present
Response to above command:

hhmmss.ss = Time of position fix (ref to UTC)
hh = hours 00..24
mm = minutes 00..59
ss.ss = seconds 00.00..59.99
a = GPS status A = valid
V = invalid
ddmm.mmmm,n = Latitude
dd = degrees 00..90
mm.mmmm = minutes 00.000..59.999
n = direction N = North

(knots)
y.y = track made good 0.0..359.9
(referenced to true north)
ddmmyy = UTC date of position fix
dd = day 01..31
mm = month 01..12
yy = year 00..99
d.d magnetic Always nulled with M12+
variation (degrees)
