中文摘要：
针对动态GPS相对定位时流动站与参考站采用不同采样率的情况，提出了在全部同步历元先行平差的基础上，将流动站上每两个最近同步历元之间的非同步数据作为一个数据段单独处理，以相邻历元相位差分值作为观测量，整体平差段内所有非同步历元流动站坐标的分段平差方法。该方法顾及了历元间差分定位所带来的相关性，有效地改善了历元间差分定位误差累积效应。算例表明，新方法更为严密可靠，并提高了流动站定位精度。
英文摘要：
In order to process the rover and the reference stations GPS data with different sampling rates, a new method is introduced. Firstly, all the epochs of rover that have syn- chronous observations with reference station are adjusted together and treated as known points. Secondly, we treat the observations of rover between two adjacent known points as a whole, use differential data between epochs of roving stations as observations, and adjust all the coordinates of roving stations in the whole together. The new method takes the correla- tion between epochs into consideration and reduces the error accumulation of difference be- tween epochs. An experiment was carried out. The result showes that new method is more rigorous and can improve the rover positioning precision.
