Extraction of Time-Varying Signals in GNSS and Geophysical Interpretation: Methods, Advances, and Challenges
Highlights What are the main findings? Maximum Likelihood Estimation (MLE) has become the standard for GNSS linear trend extraction because it jointly estimates trend parameters and stochastic noise covariance; by doing so, it corrects the up to 5–10-fold underestimation of velocity uncertainty that occurs when tempora...
