1. UTC of position fix (No use)
2. Status (A)
A=data valid, V=navigation receiver warning
3. Latitude (0000.00000 - 9000.00000)
4. N/S (N/S)
5. Longitude (00000.00000 - 18000.00000)
6. E/W (E/W)
7. Speed over ground, knots (0.00 - 9999.94)
8. Course over ground, degrees true (0.00 - 360.0)
9. Date (No use)
10. Magnetic variation, degrees (No use)
11. E/W (No use)
12. Mode indicator (A/D/E/M/S/F/P/R)
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;
S=Simulator mode
13. Navigational status indication (S/C/U/V, null)
S=Safe, C=Caution, U=Unsafe, V=Not valid
