Abstract: In this contribution, we present the triple frequency long baseline RTK algorithm and assess the contribution of QZSS to multi-GNSS RTK. The impacts of multi-GNSS broadcast orbit errors, ionosphere, and troposphere errors on the long baseline RTK are analyzed. To assess the contribution of QZSS, multi-GNSS data are collected in Japan. The analysis of the results demonstrates that with the introduction of QZSS observations, the ambiguity dilution of precision of the long baseline RTK is considerably reduced in comparison with the GPS-only or GPS+Galileo scenarios. The convergence time and instantaneous RTK performance can be significantly improved when combined with other GNSS systems.
