The latitude and longitude values in NMEA-0183 messages are
presented in degrees, minutes, and decimal minutes, in a single field:
• latitude (ddmm.mmmm)
• longitude (dddmm.mmmm)
Latitude and longitude direction values are sent in a separate field as
N, S, E, or W.

Time values in Universal Time Coordinated (UTC) are presented in
hhmmss.ss format, where hh is hours (00–23), mm is minutes, and
ss.ss is seconds and fractions of seconds.
C6.8 Reading NMEA string format
Be aware that NMEA strings can be of varying length, depending on
how the receiver is configured. Comma delimited parsing is
recommended.
