Abstract Three improvements of TurboEdit algorithm are made. The effects of different arc sections, the length of arc section and gross errors are taken into account in calculating widelane ambiguity and its variance. It is by analyzing three successive epochs that both of the combination observations determine whether the current epoch is a gross error or cycle slip. A new fitting model based on sliding window is put forward, which is more suitable for the fact that GeometryFree combination observations constitute a smooth time series. The secondary processing for divided GF arc sections can further reject gross errors. The experimental results show that the new algorithm can detect and fix the equaldistance, equalcycle and continuing happened cycle slips, can also reject successive gross errors and those less obvious gross errors.
