Cycle Slip Detection Program

This text discusses the application of high-order differences for detecting cycle slips. Let's explore this topic in greater depth. High-order differences refer to parameters in GNSS receivers that measure signal strength, while cycle slips occur when receivers fail to correctly resolve the phase of received signals, leading to accumulated errors. The method of using high-order differences for cycle slip detection effectively addresses this issue, enabling GNSS receivers to compute positional information with greater accuracy. In code implementation, this typically involves: - Calculating phase measurement differences between consecutive epochs - Applying polynomial fitting or statistical thresholds to identify abnormal variations - Implementing repair algorithms using backup observations or kinematic models The application of this method is extensive, with significant value not only in aerospace and navigation fields but also in scientific research and geological exploration. The algorithm can be implemented through time-series analysis of carrier phase data, where sudden jumps in high-order differences indicate potential cycle slips that require correction through interpolation or reinitialization procedures.
