A Modified Cycle Slip Detection Method with GNSS Doppler Assistance and Optimizing by Adaptive Threshold and Sliding Polynomial Fitting

International Journal of Aerospace Engineering, Volume 2023, Issue 1, 2023., 2023
Cycle slip determination plays an important role in high‐precision data processing and application of global navigation satellite systems (GNSS). The TurboEdit method consists of the Melbourne‐Wubbena (MW) and the geometry‐free phase (GF) combination. It can correctly detect and repair cycle slip in most cases.
