| Abstract: | Based on analyzing the properties of outliers, cycle slips and random noises, which are processed by wavelet transform, the paper presents a wavelet based outlier detecting algorithm and a wavelet based filtering algorithms. A GPS phase double difference data processing algorithm based on wavelet filtering is put forwards. The algorithm can not only reduces the ambiguity searching space, but can improve the validation of fixed ambiguities as well. |
