| 摘 要： | 为了削弱非模型化误差对单频GPS基线解算的影响,引入经验模式分解法对原始双差观测值进行自适应滤波消噪.在此基础上应用消噪后的双差观测值结合LAMBDA方法进行整周模糊度确定,进而计算基线固定解.算例分析结果表明:此方法可以有效增强基线解算的可靠性并能明显改善定位精度. |

| Abstract: | In order to weaken the influence of the un-modeled errors on the single frequency GPS baseline solution,the empirical mode decomposition method was proposed for adaptive filtering de-nosing of original double difference observations.The denoised double difference observation data and LAMBDA algorithm were applied to determine the integer ambiguity,based on which the baseline fixed solution can be obtained.The case study results show that the proposed method can effectively enhance the reliability of baselin... |
