Key parameters of GNSS RTK positioning.
| Parameter | Settings |
| Observations | Double-differenced dual-frequency carrier-phase and pseudorange (GPS L1 and L2), Galileo E1 and E5A, and BDS (B1 and B2) | Cutoff angle | 12° | Observation weighting scheme | An elevation-dependent scheme based on the cosecant function | Baseline length | About 100 m | Estimation method | Kalman filter | Antenna phase center offsets | Corrected with Antex igs14.atx [38] | Atmospheric delays | Eliminated in double-differencing | Ambiguity | Estimated and fixed to integers with Lambda |
