Web1 jan. 2024 · For these data, we adopt the ionosphere-free (IF) combination to detect cycle slips. The IF combination can reduce the impact of the ionosphere by nearly 99%, thereby providing a detection value precise enough to detect the cycle slips with the magnitude of one or two cycles. However, the IF combination has two main drawbacks.
