| 摘 要： | 基于TurboEdit算法中的MW组合，利用卡尔曼滤波分离宽巷模糊度以提高模糊度精度。利用移动窗口的多项式拟合对原GF组合中的多项式拟合进行改进，并对周跳的浮点解进行计算。使用GPS数据检测方法的正确性，结果表明，该方法能探测并修复小周跳、大周跳以及多个周跳。

| Abstract: | This method is an improvement based on TurboEdit algorithm. Firstly, it uses the Kalman filter to separate the ambiguity resolution in order to improve the precision of the ambiguity, thus to set up the foundation for detecting the repairing the cycle slips properly; Secondly, this method uses a fixed length sliding window fitting model to improve the polynomial fitting of the original GF combination; Thirdly, it uses the fixed length sliding window fitting model to calculate the floating solution of the cycle slips while repairing the cycle slips. The validity of this method has been tested by the GPS data. The results show that this method is valid for the detection and repair for small, big and multiple cycle slips. |
