Empirical mode decomposition method for single frequency GPS baseline solutions
Chengquan Xu · Journal of Hohai University · 2011
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 baseline solution and obviously improve the positioning precision.
