摘要
利用小波分析方法对常用的GPS周跳检测量进行了周跳探测,获得了小波方法所能探测到的最小周跳值,并与高次差法进行了对比,提出了利用小波变换探测出周跳后如何直接进行周跳修复的方法。计算结果表明,该方法是可行的。
The commonly-used GPS cycle-slip detecting observations are used to detect cycle slips by wavelet method. The minimum cycle slips that can be detected by wavelet transform are obtained, and the wavelet method is compared with high order time differences. Doubledifference phase data of cycle slip occurring twice in short time is calculated. Results prove that wavelet method works also well. A method about how to repair cycle slips based on wavelet transform is presented. Then tests are carried out. Results indicate that the method is feasible.
