| 6 | GPS Quality indicator: 0: Fix not valid 1: GPS fix 2: Differential GPS fix, OmniSTAR VBS 4: Real-Time Kinematic, fixed integers 5: Real-Time Kinematic, float integers, OmniSTAR XP/HP or Location RTK |
above is the sixth information in GGA data, would you please help me to discribe the differences among the different value. in our project the SPS 855 are used, but we use the no.5 Location RTK as the correct solution. but sometimes the no.2(Differential GPS fix) appears. actually, we are using the GBAS. so I want someone to help me explain the difference in detail. thanks a lot.
