| 摘 要： | 周跳的探测和修复是GPS相对定位数据处理过程中的一个重要组成部分,修复周跳首先要探测周跳。根据小波变换对信号奇异性检测的原理,对GPS相对定位中载波相位差分观测值进行周跳的探测,并结合实验数据进行计算机仿真分析。证明小波技术探测载波相位差分观测值中的周跳效果明显,其自动化程度较高、定位准确,在实际应用中具有很好的实用价值。

| Abstract: | The detection and repair of cycle-slips are important parts in processing GPS data.According to the principle of signal oddity detection by wavelet transform,wavelet transform is used to detect the cycle-slip of the GPS carrier phase differential observations in GPS relative positioning.The computer simulation results demonstrate that the effect of the method is very obvious.The degree of automatization is higher and the position is more exact with the presented method than with the routine methods.The method of wavelet detection is practical for application. |
