1. GPS Quality Indicator:

0 = Fix not available or invalid

1 = GPS SPS Mode, fix valid

2 = Differential GPS, SPS Mode, fix valid

3 = GPS PPS Mode, fix valid

4 = Real Time Kinematic. System used in RTK

mode with fixed integers

5 = Float RTK. Satellite system used in RTK

mode with floating integers

6 = Estimated (dead reckoning) mode

7 = Manual Input mode

8 = Simulator mode

The GPS Quality indicator shall not be a null

field.

2. Horizontal dilution of precision:

The system adds leading digits as required.
