高精度实时轨道钟差是精密定位的基础,针对单个分析中心实时产品不连续不抗差的问题,本文研究并验证了多分析中心GNSS实时产品的稳健综合方法。试验结果表明:融合多分析中心的四系统综合产品完整率从27.53%~99.10%提升到99.13%~100%;综合轨道和钟差产品精度优于大多数分析中心,四系统轨道精度平均提升幅度43.6%~55.7% ,钟差精度平均提升幅度12.3%~24.5%;精密动态定位的收敛时间和定位精度亦与最优分析中心相当,其中收敛时间较单分析中心平均缩短42.1%,东、北和高三个方向的定位精度分别为2.4 cm、3.9 cm和4.8 cm,相对分析中心产品定位结果平均提升32%、14%和24%。本文方法可为卫星导航系统实时高精度应用提供技术支撑。
High-precision real-time orbit and clock error are the foundation of precise positioning. To address the issue of instability in real-time products from a single analysis center, this paper studies and validates a comprehensive method for multi-GNSS real-time orbit and clock products. Experimental results show that the integrated product from multiple analysis centers avoids service discontinuity caused by data interruptions in a single analysis center, with the completeness rate of four-system products increasing from 27.53%~99.10% to 99.13%~100%. The accuracy of the integrated orbit and clock error products is superior to that of most analysis centers, with an average improvement in one-dimensional averaging accuracy of the four-system orbit ranging from 43.6% to 55.7%, the average improvement in clock accuracy is in 12.3%~24.5%; The convergence time and positioning accuracy of the integrated product’s precise dynamic positioning are comparable to those of the optimal analysis center. Specifically, the convergence time is on average 42.1% shorter than that of a single analysis center. The positioning accuracies in the east, north and height directions are 2.4 cm, 3.9 cm and 4.8 cm, respectively, with relative improvements of 32%, 14%, and 24% compared to the positioning results of the analysis center product. The conclusion indicates that the method proposed in this paper can provide technical support for real-time high-precision applications of satellite navigation systems.
