| 摘 要： | 针对GNSS多模解算不仅可充分利用各系统优势，还能提高导航定位结果的精度和可靠性，但GPS/BDS之间未模型化的系统偏差将严重损害系统之间的兼容性与互操作性的情况。详细研究了BDS系统未模型化的天线相位中心偏差对解算结果的影响，并根据实测数据对推导的结论进行验证。结果表明，在本文的实验条件下，GPS与BDS之间确实存在较为显著的系统误差；消除天线相位中心偏差影响后，此系统偏差依然存在。

| Abstract: | Multi-GNSS can not only make full use of the advantages of different systems, but also improve the accuracy and reliability of GNSS navigation and positioning. Nevertheless, the unmodeled systematic deviation between GPS and BDS undermines inner compatibility and inter-operability. Focusing on this problem, the influence from unmodeled antenna phase center offsets of BDS on baseline solution is researched deeply in this paper, and the conclusion is validated with observation data. The results of our experiments show that systematic deviation between GPS and BDS indeed exists. After eliminating the influence of antenna phase center offsets, this systematic deviation remains. |
