NOTE 1
All GPS quality indicators in headings 1 through 8 are considered “valid”.
The heading “0” is the only “invalid” indicator. The GPS quality indicator field
should not be a null field.
0 = fix not available or invalid
1 = GPS SPS mode
2 = differential GPS, SPS mode
3 = GPS PPS mode
4 = Real Time Kinematic. Satellite system used in RTK mode with fixed integers
5 = Float RTK. Satellite system used in RTK mode with floating solution
6 = Estimated (dead reckoning) mode
7 = Manual input mode
8 = Simulator mode
