| 摘 要： | 针对北斗导航卫星系统（BDS）不同类型卫星观测数据的特点，对TurboEdit方法进行改进。在利用M-W组合观测值检测时，使用固定窗口的滑动求解方法代替其原有的递推求解方法。将原有的电离层残差组合检测方法改进为双频电离层残差的相邻历元求差法，并且可以根据不同类型的卫星选择不同的检测参数。改进后的算法对GEO/IGSO/MEO卫星均可达到良好的检测效果。算法验证表明，该算法可以有效检测并修复1周的小周跳，也可以检测修复双频点等周大小的小周跳，修复精度可达到0.1周以内。

| Abstract: | An improved TurboEdit Algorithm for BDS is analyzed and validated based on the characteristics of BDS with three types of satellites. A fixed window sliding method is used instead of the original recursive method for detecting cycle slips with M-W combination observations. The original ionosphere residual combination detection method is improved by including the adjacent epoch differential method for double-frequency ionosphere residuals, the detection parameters can be selected for GEO/IGSO/MEO satellites. During actual data processing, the improved algorithm is more stable and yields more accurate detection results than the original algorithm, especially in detection of small cycle slips. Also, the improved algorithm can effectively compensate for the original algorithm that does not easily detect small cycle-slips. Experimental results show that the improved algorithm can effectively detect all kinds of cycle slips such as equal-cycle, small cycle slips and big cycle slips. The repair precision can reach the 0.1 cycle. |
