Generalized Matérn Process for GNSS Coordinate Series Noise Modeling

GNSS coordinate series noise modeling is essential for reliable geophysical signal estimation and uncertainty assessment. The generalized Gauss–Markov (GGM) noise model and the Matérn process (MP) noise model are widely used to describe low-frequency spectral flattening in GNSS coordinate series, but they differ in the...

PWVGAT: Graph Attention Network for Spatial Inference of GNSS Precipitable Water Vapor Over Irregular Station Networks

Precipitable water vapor (PWV) derived from Global Navigation Satellite System (GNSS) stations provides millimeter-level accuracy under all weather conditions but is limited to discrete site locations. Extending these observations into spatially continuous fields remains challenging because conventional interpolation a...
