摘要 阐述了多普勒探测周跳的原理,采用IGS跟踪站1 s采样率的观测数据,利用TE-QC软件分别生成2 s、3 s、4 s、5 s、10 s、15 s和30 s采样率的另外几组观测数据。确定了这几组数据无周跳,人为地加入不同周数的周跳,利用多普勒方法对其进行周跳探测,并对结果进行分析与讨论。探讨了多普勒方法探测周跳的效果,给出在不同采样率下的周跳探测精度。 We describe the basic principle of Doppler method for detecting cycle slips, Observation data of sampling rate of 1 s from an IGS( International GNSS Service) tracking station is generated into the other groups of observation data of 2 s, 3 s, 4 s, 5 s, 10 s, 15 s and 30 s sampling interval using TEQC software. Under the premise of no cycle slips existing in these groups of observation data, some different cycle slips are intentionally added into the data. Doppler method is used to detect cycle slips in the data, the experiment results are analyzed and discussed, and accuracy of Doppler method is given.
