3. Month, 01 to 12 (UTC)
4. Year (UTC)
5. Local zone hours, 00h to
±
13h
6. Local zone minutes, 00 to +59 (see Note)
NOTE: Local time zone is the magnitude of hours plus the magnitude of minutes added, with the sign of local
zone hours, to local time to obtain UTC. Local zone is generally negative for East longitudes with local
exceptions near the international date line.

4. Mode indicator (see Note 1)
5. Total number of satellites in use, 00-99
6. HDOP (see Note 2)
7. Antenna altitude, m, re: mean-sea-level (geoid)
8. Geoidal separation, m (see Note 3)
9. Age of differential data (see Note 4)
10. Differential reference station ID (see Note 4)
11. Navigational status indicator (see Note 5)
NOTE 1: Mode indicator. A variable length valid character field type with the first three characters currently
defined. The first character indicates the use of GPS satellites, the second character indicates the use
of GLONASS satellites and the third indicate the use of Galileo satellites. If another satellite system is
added to the standard, the mode indicator will be extended to four characters, new satellite systems
should always be added on the right, so the order of characters in the mode indicator is: GPS,
GLONASS, Galileo, other satellite systems in the future. The characters should take one of the
following values:
A = Autonomous. Satellite system used in non-differential mode in position fix;
D = Differential. Satellite system used in differential mode in position fix;
E = Estimated (dead reckoning) mode;
F = Float RTK. Satellite system used in real time kinematic mode with floating integers;
M = Manual input mode;
N = No fix. Satellite system not used in position fix, or fix not valid;
P = Precise. Satellite system used in precision mode. Precision mode is defined as: no deliberate
degradation (such as selective availability) and higher resolution code (P-code) is used to compute
position fix. P is also used for satellite system used in multi-frequency, SBAS or Precise Point
Positioning (PPP) mode;
R = Real Time Kinematic. Satellite system used in RTK mode with fixed integers;
