摘　　要：阐述了周跳探测的重要性,分析了多小波在信号处理方面比单小波更有优势,基于此,利用多小波变换模极大值与信号奇异性之间的关系模型,写出了多小波在GPS周跳探测中的具体操作步骤。最后应用于GPS双差观测量,实验结果表明多小波变换在GPS相位观测值周跳探测中的有效性。It elaborates the importance of cycle slip detection and analysis the advantage of multi-wavelets in signal processing than single wavelets.Based on this,using the relationship model of the maxima value of multi-wavelet transform and the signal singularity,it writes specific steps of multi-wavelet in GPS cycle slip detection.Finally,with the experiment of GPS double difference observation,the result shows the effectiveness of the multi-wavelet transform in GPS phase observations of cycle slip detection.
