基于星历计算的多普勒积分法的周跳探测与修复

摘要

A new ephemeris calculation method based on Doppler integration is proposed in order to detect and repair cycle slips. This method use ephemeris data to calculate Doppler integration between neighboring epochs accurately. In the condition of static observation, with this method we can detect and repair cycle slips from single-frequency observation data of large sampling interval easily, without Doppler observations of receiver. The example of IGS observation data shows that with this new method the single cycle slip and continuous cycle slips from IGS data of 180 seconds sampling interval can be detected and repaired easily.%提出一种新的多普勒积分的周跳探测与修复方法,该方法利用星历数据精确计算相邻历元的多普勒积分,并利用计算的多普勒积分值探测与修复周跳.在静态观测条件下,该方法对于大采样间隔的单频观测数据仍然能够成功探测与修复周跳,并且无需接收机的多普勒观测值.实测数据算例的结果表明,基于星历计算的多普勒积分法对于180s采样间隔的单频数据仍能有效探测单周和连续周跳并成功修复.
