摘 要: | 针对Melbourne-Wubbena(Mw)组合和Geometry-Free(GF)组合探测、修复周跳的优点,提出联合使用这两种组合探测和修复周跳的基于固定宽度的滑动窗口的改进方法。改进方法能探测出小周跳、等值周跳、连续周跳、三周跳,也能探测出电离层残差法不易探测出的特殊组合周跳,如(9、7)组合,(3、2)组合等,更适合实际的应用。

Abstract: | On the basis of cycle-slip detection and correction method using combination of MW and GF, a new idea was put forward--slip window based on fixed width according to actual situation. The new method could detect small cycle-slip, equivalent cycle--slip, sequential cycle--slip, as well as some special combinations that could not be detected by the ionosphere residual method, such as (9.7), (3. 2). |
