在现代测量中,GPS已成为测绘领域的主要工具,但周跳现象是影响GPS测量精度的来源之一,因此对周跳产生的原因和特性进行了分析,并且结合仿真实验分析且说明了小波用于周跳探测的理论依据。选择不同的小波对GPS相位观测值周跳进行了实验,表明经过小波处理的方法进行周跳探测,其精度更高一点。 更多还原

【Abstract】 In modern measurement,GPS has became surveying and mapping area of main tools,but Cycle-slip phenomenon is one of the sources of affect measurement precision of GPS,so the causes and characteristics of cycle slip were analyzed.And combination of simulation experiment analysised and described the theoretical basis of wavelet for cycle slip detection.Selecting different Wavelets for cycle slips in GPS phase observations in the experiment,indicated its accuracy was higher that after Wavelet process... 更多还原
