Abstract:To evaluate the receiver measurement noise of the new signals B1C and B2a of BDS-3 in kinematic mode, we determine the measurement noises of the new signals by zero-baseline kinematic test and compare the results with other GNSS signals. Meanwhile, we compare the kinematic results with the static mode. In the kinematic test, the RMS values of pseudorange noises of MEO satellites on B1C and B2a frequencies of BDS-3 are 8 cm and 4 cm, respectively, and the carrier phases are 0.061 cm and 0.082 cm, respectively. The measurement noise of IGSO satellites increases slightly. The pseudorange noise of each frequency of the four constellations are obviously different, but the phase noises range is not large. Although there is a decline in kinematic observation data quality, the overall pseudorange noises on B1C and B2a frequencies are not significantly different compared to static noises. However, the difference of the carrier phase noises is more significant.
