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.

四星QZSS对多GNSS长基线RTK的贡献

摘要 在这个贡献中，我们提出了三频长基线 RTK 算法并评估了 QZSS 对多 GNSS RTK 的贡献。分析了多GNSS广播轨道误差、电离层和对流层误差对长基线RTK的影响。为了评估 QZSS 的贡献，在日本收集了多 GNSS 数据。结果分析表明，与仅使用 GPS 或 GPS+Galileo 方案相比，随着 QZSS 观测的引入，长基线 RTK 精度的模糊稀释大大降低。当与其他 GNSS 系统结合时，收敛时间和瞬时 RTK 性能可以得到显着改善。
